Concepts of Biology 2013-04-25T00:00:00Z The Hardy-Weinberg model of population dynamics is an algebraic representation of the relationships among genotype frequencies, F, and the probability of the dominant allele A, p, and the recessive allele a, q. Biology for AP Courses 2022-06-09T00:00:00Z In males, a recessive allele on the single X chromosome is usually expressed. Miller & Levine Biology 2018-01-01T00:00:00Z Mendel called the dominant allele the expressed unit factor; the recessive allele was referred to as the latent unit factor.

Concepts of Biology 2013-04-25T00:00:00Z The recessive allele will remain “latent” but will be transmitted to offspring by the same manner in which the dominant allele is transmitted. Biology for AP Courses 2022-06-09T00:00:00Z In order for a recessive allele to be expressed in females, it must be present on both of the X chromosomes. Miller & Levine Biology 2018-01-01T00:00:00Z For example, a disease that is caused by a rare, recessive allele might exist in a population, but it will only manifest itself when an individual carries two copies of the allele. Biology for AP Courses 2022-06-09T00:00:00Z Sometimes, the recessive allele occurs more frequently than the dominant allele. Miller & Levine Biology 2018-01-01T00:00:00Z An organism that has both a dominant allele and a recessive allele for a trait will show the dominant characteristic. Miller & Levine Biology 2018-01-01T00:00:00Z This progressive disease has two causes: an autosomal recessive allele, which causes neonatal ALD, and a mutation in the ABCD1 gene located on the X chromosome.

Miller & Levine Biology 2018-01-01T00:00:00Z Mendel found that the allele for tall plants was dominant over the recessive allele for short plants, and the allele for yellow pods was dominant over the recessive allele for green pods. Miller & Levine Biology 2018-01-01T00:00:00Z About one fourth of the F2 plants showed the trait controlled by the recessive allele. Miller & Levine Biology 2018-01-01T00:00:00Z |
