| 单词 | autosome |
| 例句 | An individual with the appropriate number of chromosomes for their species is called euploid; in humans, euploidy corresponds to 22 pairs of autosomes and one pair of sex chromosomes. Concepts of Biology 2013-04-25T00:00:00Z Rather than a gain or loss of autosomes, variations in the number of sex chromosomes are associated with relatively mild effects. Biology for AP Courses 2022-06-09T00:00:00Z The remaining 44 human chromosomes are autosomal chromosomes, or autosomes. Miller & Levine Biology 2018-01-01T00:00:00Z Other examples of autosome recessive genetic illnesses include the blood disorder sickle-cell anemia, the fatal neurological disorder Tay–Sachs disease, and the metabolic disorder phenylketonuria. Anatomy and Physiology 2013-06-19T00:00:00Z Divergence was more uniformly distributed along the Z chromosome and did not show the distinct islands of divergence characterizing most autosomes; the Z chromosome contained approximately 35% of all fixed sites in the genome. The genomic landscape of species divergence in Ficedula flycatchers 2012-12-05T15:23:01.900Z Monosomic human zygotes missing any one copy of an autosome invariably fail to develop to birth because they have only one copy of essential genes. Concepts of Biology 2013-04-25T00:00:00Z In addition to 22 homologous pairs of autosomes, human females have a homologous pair of X chromosomes, whereas human males have an XY chromosome pair. Biology for AP Courses 2022-06-09T00:00:00Z Furthermore, the team determined that Papuans have more Denisovan DNA on their autosomes, inherited equally often from both parents, than on their X chromosomes, inherited twice as often from the mother. Genome Brings Ancient Girl to Life 2012-08-30T20:02:00Z Our calculation of α assumes that a single speciation time applies across the genome, attributing differences between the X chromosome and autosomes to the factors mentioned above. Insights into hominid evolution from the gorilla genome sequence 2012-03-07T18:21:00.777Z We find over four times as many adaptive fixations on the chromosome relative to autosomes. The Drosophila melanogaster Genetic Reference Panel 2012-02-08T18:51:32.053Z But both men and women pass along the same number of autosomes. The Case of the Missing Polygamists 2012-01-06T18:15:08.430Z Until now, we have only considered inheritance patterns among non-sex chromosomes, or autosomes. Biology for AP Courses 2022-06-09T00:00:00Z This difference is expected because the population size of the chromosome is three quarters that of autosomes, and the chromosome can experience greater purifying selection because of exposure of deleterious recessive alleles in hemizygous males. The Drosophila melanogaster Genetic Reference Panel 2012-02-08T18:51:32.053Z Recombination is the major predictor of polymorphism on the chromosome and autosomes; however, the significant effect of autosomal chromosome region remains after accounting for variation in recombination rates between centromeric and non-centromeric regions. The Drosophila melanogaster Genetic Reference Panel 2012-02-08T18:51:32.053Z New -linked mutations are directly exposed to selection each generation in hemizygous males, and the chromosome has greater recombination than autosomes; both of these factors could contribute to this observation. The Drosophila melanogaster Genetic Reference Panel 2012-02-08T18:51:32.053Z This means that by comparing the genetic differences between X-chromosomes and autosomes you can estimate the effective population size of men who successfully reproduced compared to women. The Case of the Missing Polygamists 2012-01-06T18:15:08.430Z Monosomic human zygotes missing any one copy of an autosome invariably fail to develop to birth because they lack essential genes. Biology for AP Courses 2022-06-09T00:00:00Z Genome-wide molecular population genetic analyses show that patterns of polymorphism, but not divergence, differ by autosomal chromosome region, and between the X chromosome and autosomes. The Drosophila melanogaster Genetic Reference Panel 2012-02-08T18:51:32.053Z |
