例句 | Figure 8.8 A test cross can be performed to determine whether an organism expressing a dominant trait is a homozygote or a heterozygote. Concepts of Biology 2013-04-25T00:00:00Z Figure 12.5 A test cross can be performed to determine whether an organism expressing a dominant trait is a homozygote or a heterozygote. Biology for AP Courses 2022-06-09T00:00:00Z Dominant lethal inheritance patterns are much more rare because neither heterozygotes nor homozygotes survive. Anatomy and Physiology 2013-06-19T00:00:00Z These people, known as CCR5Δ32 homozygotes, appear healthy and are highly resistant to HIV infection. Did CRISPR help—or harm—the first-ever gene-edited babies? 2019-08-01T04:00:00Z But the 1% who inherit the mutation from both parents—so-called homozygotes—are highly resistant: Studies show that if they’re exposed to HIV, they’re 100 times less likely to become infected. Ethics aside, does the CRISPR baby experiment make scientific sense? 2018-11-28T05:00:00Z Coat color depends on the A gene, which shows dominance, with the recessive homozygote showing a different phenotype than the heterozygote or dominant homozygote. Concepts of Biology 2013-04-25T00:00:00Z For crosses between heterozygous individuals with a recessive lethal allele that causes death before birth when homozygous, only wild-type homozygotes and heterozygotes would be observed. Biology for AP Courses 2022-06-09T00:00:00Z Cultivated lines are homozygotes for the allele resulting in a biennial life cycle. The genome of the recently domesticated crop plant sugar beet (Beta vulgaris) 2014-01-22T18:21:48.441Z The study found that CCR5Δ32 homozygotes were about 20% less likely than the rest of the population to reach age 76. Did CRISPR help—or harm—the first-ever gene-edited babies? 2019-08-01T04:00:00Z Let us suppose for instance, that the population consists of p homozygotes of one kind, r homozygotes of the other kind, and 2 q heterozygotes. Mendelism Third Edition An individual may be a homozygote with respect to one factor and a heterozygote with respect to another. Applied Eugenics For instance, the recessive lethal Curly allele in Drosophila affects wing shape in the heterozygote form but is lethal in the homozygote. Biology for AP Courses 2022-06-09T00:00:00Z An albino is a homozygote; that is, all its gametes are carrying the character of albinism and none of them bear the alternative character —the allelomorph—-of pigmentation. The Project Gutenberg Encyclopedia Volume 1 of 28 The dominant lethal inheritance pattern is one in which an allele is lethal both in the homozygote and the heterozygote; this allele can only be transmitted if the lethality phenotype occurs after reproductive age. Biology for AP Courses 2022-06-09T00:00:00Z The probability of the homozygote or the heterozygote is 1/4 + 1/2 = 3/4 using the sum rule. Biology for AP Courses 2022-06-09T00:00:00Z In the second generation, only two individuals, both of whom are homozygote in B, reproduce. Biology for AP Courses 2022-06-09T00:00:00Z However, homozygotes with this mutation are less prone to malaria infection, a disease that historically was the most widespread deadly disease among humans.
