Catholic Churchmen in Science The heredity block was a racial quantity, the germ plasm, but not just that. The Impossible Voyage Home We take the living germ plasm, the sperm and the egg, and we modify it. The Thing in the Attic How can we reconcile the mutation and the variability of the germ plasm, with its immortality and its eternal transmission? The Forerunners Once these have had their germ plasm preserved, they are sold to other farms to create satellite populations. 2010-01-07T18:35:00Z Now, it has been found that a variation arising in the germ plasm, no matter what its cause, may affect any stage in the development of the next individuals that arise from it.

A History of Science, Volume 5(of 5) Aspects Of Recent Science It is to nature what in Weismann's theory the germ plasm is to the somatic cell. Monophysitism Past and Present A Study in Christology In each individual, the cells of the germ plasm continue the life of the parents, of which, in the fullest sense of the word, they are living portions. The Forerunners "Pretending you were going to give me a healthy child," Hank raved on, "when all the while you knew it would be—either in body or germ plasm—a thing like that!" The Moon is Green We see, too, more clearly that the sorting out of factors in the germ plasm is a very different process from the influence of these factors on the development of the organism. A Critique of the Theory of Evolution For clearly the fact that the separated egg-cells grow into complete individuals shows that Weismann's theory, according to which one of the cells contained only body plasm, the other only germ plasm, is quite untenable. A History of Science, Volume 5(of 5) Aspects Of Recent Science Since Weissmann's time, however, every Lamarckian feels it necessary to suggest some method by which the altered body of the parent can produce modifications in the germ plasms from which the young are to spring. The Meaning of Evolution Let us add that thought, too, propagates itself throughout mankind, in like manner with the germ plasm. The Forerunners Life is thus maintained by a continuous stream of germ plasm and is not periodically interrupted in its course, as it seems to be, by death. Introduction to the Science of Sociology The reckless use of the phrase "unit character" has done much to mislead the uninitiated as to the effects that a single change in the germ plasm may produce on the organism. A Critique of the Theory of Evolution In both instances germ plasm of wide genetic difference is incorporated into a new propagating breeding stock. Northern Nut Growers Association Report of the Proceedings at the 43rd Annual Meeting Rockport, Indiana, August 25, 26 and 27, 1952 Let us explore these new fields of nut germ plasm which lie all about us, pull these old nuts apart genetically and recombine their good with the good of other nuts into new varieties. Northern Nut Growers Association Report of the Proceedings at the Thirty-Seventh Annual Report Wooster, Ohio, September 3, 4, 5, 1946 Every thought, once expressed, leads in the human community a life independent of its creator; undergoes development in other minds; and has, like the germ plasm, an immortal life.

The Snowshoe Trail Amphimixis: the mingling of the germ plasm of two individuals. Explanation of Terms Used in Entomology Real progress is in the breed—in the germ plasm. Introduction to the Science of Sociology In a word, Johannsen's work shows that the frequency distribution of a pure line is due to factors that are extrinsic to the germ plasm. A Critique of the Theory of Evolution This "germ plasm" is a divine gift to be held in trust and carefully guarded from the odium of taint, to be handed down to the sons and daughters of the next generation. The Mother and Her Child Hence, women have up to a recent time been more sinned against than sinning if they passed on defective germ plasm or doomed their children to suffering lives.

How to Live Rules for Healthful Living Based on Modern Science It exists only in the psychic vacuum of antenatal life, or perhaps only in the potentiality of the germ plasm. Introduction to the Science of Sociology It does not matter then which individuals in a pure line are used to breed from, for they all carry the same germ plasm. A Critique of the Theory of Evolution It is not because the child can inherit directly from its parent, but rather because both child and parent have come from the unfolding of two bits of the same germ plasm. The Story of the Living Machine A Review of the Conclusions of Modern Biology in Regard to the Mechanism Which Controls the Phenomena of Living Activity It is true that what Dr. Caleb W. Saleeby well calls "racial poisons" are often the cause of the damaged germ plasm that starts the handicapped human being along his devious course. The Family and it's Members We are the trustees of the racial germ plasm that we carry. How to Live Rules for Healthful Living Based on Modern Science These three principles are the three corner stones of heredity as we know it today, the principles of the independent unit-characters each derived from a determiner in the germ plasm. Introduction to the Science of Sociology An individual is picked out from the population in order to get a particular kind of germ plasm. A Critique of the Theory of Evolution Being born with the individual, they can not be produced by conditions affecting him, but rather to something affecting the germ plasm from which he sprung. The Story of the Living Machine A Review of the Conclusions of Modern Biology in Regard to the Mechanism Which Controls the Phenomena of Living Activity Meanwhile, the family interest is keen and must become more active and commanding in ridding society of the inducing causes of diseased germ plasm. The Family and it's Members Meantime, it is probably true that the female, as mother of the race, is more important biologically than the male, since she both furnishes germ plasm and nourishes the newly conceived life. Woman in Modern Society What is the relation, as conceived by the eugenists, as between germ plasm and culture? Introduction to the Science of Sociology Since self-fertilization is the normal process in this bean the purity of the germ plasm already existed when Johannsen began to experiment. A Critique of the Theory of Evolution The nature of the germ plasm controls the nature of the individual, and congenital variations must consequently be due to its variations. The Story of the Living Machine A Review of the Conclusions of Modern Biology in Regard to the Mechanism Which Controls the Phenomena of Living Activity Before I approach the solution of this problem, it may be advisable to recall in a few words to my readers the theory of the immortality of the germ plasm. Scientific American Supplement, No. 810, July 11, 1891 The jolt carried through all the intricacies of the nerves, jarred the soul within the man, and seemingly registered in the germ plasm itself an impression that could be recalled, in dreams, ten generations hence. The Sky Line of Spruce The so-called "acquired characters" or modifications of original nature through experience, he points out, are transmitted not through the germ plasm but through communication. Introduction to the Science of Sociology "And that the germ plasm is different from the parthenogenetic egg?" The Lost World But it is not so easy to see how this germ plasm can undergo variation. The Story of the Living Machine A Review of the Conclusions of Modern Biology in Regard to the Mechanism Which Controls the Phenomena of Living Activity That applies to the physical changes; in the mental powers the restoration will be even more rapid, because we have made less change in the psychic elements of the germ plasm. City of Endless Night These results tend to show that factors are not indivisible units, and segregation is rather the difficulty of chromatin or germ plasm from different race uniting together. Hormones and Heredity Are the apparent differences between men and women, white and colored, John and James, those which arise from differences in the germ plasm or from differences in education and in cultural contacts? Introduction to the Science of Sociology The ovary is the organ for the preservation and maturation of the germ plasm, that treasure which the body is built but to cherish and hand on as a sacred heirloom. The Glands Regulating Personality In other words, in order to explain congenital variations we must account for variations in the germ plasm. The Story of the Living Machine A Review of the Conclusions of Modern Biology in Regard to the Mechanism Which Controls the Phenomena of Living Activity Until you have thoroughly failed to see tradition being handed on from parents, teachers, priests, and uncles, it is a solecism of the worst order to ascribe political differences to the germ plasm. Public Opinion "Still," considered Kennedy, "there might have been something latent in her family germ plasm back of the time through which you could trace it?" The War Terror "One doesn't go around broadcasting data on the variations of one's germ plasm," Brainard said. The Lani People If the germ plasm is the organ of biological heredity, speech and its derivatives are the organs of social heredity! The Foundations of Personality The first is by the direct influence upon the germ plasm of certain unknown external conditions. The Story of the Living Machine A Review of the Conclusions of Modern Biology in Regard to the Mechanism Which Controls the Phenomena of Living Activity The second method by which the variations of germ plasm may arise is apparently of more importance. The Story of the Living Machine A Review of the Conclusions of Modern Biology in Regard to the Mechanism Which Controls the Phenomena of Living Activity Now, the two parents are never exactly alike, and hence the germ plasm which each contributes to the offspring will not be exactly alike. The Story of the Living Machine A Review of the Conclusions of Modern Biology in Regard to the Mechanism Which Controls the Phenomena of Living Activity Whatever changes had taken place in the somatic characteristics of mankind since the Exodus, they had not altered the compatibility of human germ plasm. The Lani People The facts which we have noted of the continuity of germ plasm have during the last fifteen years led many biologists to deny the possibility of the latter. The Story of the Living Machine A Review of the Conclusions of Modern Biology in Regard to the Mechanism Which Controls the Phenomena of Living Activity If the germ plasm is wholly stored within the reproductive gland, it is certainly in a position to be only slightly affected by surrounding conditions which affect the animal. The Story of the Living Machine A Review of the Conclusions of Modern Biology in Regard to the Mechanism Which Controls the Phenomena of Living Activity Now if this peculiarity were a congenital variation it would be already represented in the germ plasm, and consequently it would be inherited by the next generation. The Story of the Living Machine A Review of the Conclusions of Modern Biology in Regard to the Mechanism Which Controls the Phenomena of Living Activity Now whether this undifferentiated germ plasm, as we will now call it, is distributed all over the body, or is collected at certain points, is immaterial to our purpose. The Story of the Living Machine A Review of the Conclusions of Modern Biology in Regard to the Mechanism Which Controls the Phenomena of Living Activity That was a marvelous thing about flowers—wherever one went in the universe, plants used the same methods to fertilize their seed and spread their germ plasm. The Lani People This explanation is that some of the chromatin material or germ plasm is handed down from one generation to another, and is stored temporarily in the nucleii of the reproductive cells. The Story of the Living Machine A Review of the Conclusions of Modern Biology in Regard to the Mechanism Which Controls the Phenomena of Living Activity Probably no one, however, holds this position to-day, and it is the general belief that the germ plasm may be to some slight extent modified by external conditions. The Story of the Living Machine A Review of the Conclusions of Modern Biology in Regard to the Mechanism Which Controls the Phenomena of Living Activity This fact of the transmission of the hereditary substance from generation to generation is known as the theory of the continuity of germ plasm. The Story of the Living Machine A Review of the Conclusions of Modern Biology in Regard to the Mechanism Which Controls the Phenomena of Living Activity This germ plasm is handed on from generation to generation with all its variations, and hence the variations will be added permanently to the machine. The Story of the Living Machine A Review of the Conclusions of Modern Biology in Regard to the Mechanism Which Controls the Phenomena of Living Activity But the germ plasm within the reproductive glands is not, so far as we can see, subject to the influence of an increased use, for example, in the arm muscles. The Story of the Living Machine A Review of the Conclusions of Modern Biology in Regard to the Mechanism Which Controls the Phenomena of Living Activity They insist that all inherited variations are congenital, and due therefore to direct variations in the germ plasm, and that all instances of seeming inheritance of acquired variations are capable of other explanation. The Story of the Living Machine A Review of the Conclusions of Modern Biology in Regard to the Mechanism Which Controls the Phenomena of Living Activity Of course, if such variations do occur in the germ plasm they will become congenital variations of the next generation, since the next generation is the unfolding of the germ plasm. The Story of the Living Machine A Review of the Conclusions of Modern Biology in Regard to the Mechanism Which Controls the Phenomena of Living Activity A machine, either through the direct influence of the environment, or as a result of sexual combination of germ plasm, shows a variation from its parents.
