Answer #1

According to the condition given in question

we have, two alleles B1 and B2

frequency of allele B1 is 0.72, frequency of allele B2 is 1-0.72 = 0.28.

now in order to find frequency of heterozygotes, we have the formula, 2pq

here p = B1 = 0.72, q = B2 = 0.28.

then frequency of heterozygotes = 2pq = 2B1B2 = 2 x 0.72 x 0.28 = 0.40

Thus the frequency of heterozygote is 0.40

    Problem Description: A gene with two alleles (e.g. A and a) is responsible for a dominant trait in Hellbenders (Cryptobranchus alleganiensis). AA individuals have a normal phenotype, while those with aa lack the trait. Heterozygotes have phenotypes that are identical to AA individuals. Although aa individuals have lower survivorship (15%) than those with the “normal” trait (35%), they have higher fecundity over their lifetime (100 individuals for aa; compared to 48 for AA and Aa). Assume the allele frequency of...

    2. Which of the following correctly describes how inbreeding will affect genotype and allele frequencies in Hardy-Weinberg populations? Genotype and allele frequencies will be unaffected. The frequency of heterozygotes will decrease, but allele frequencies will be unaffected. The frequency of homozygotes will increase, and deleterious alleles will decrease. Beneficial alleles will increase in frequency, as well as the genotypes containing those alleles. Genotype frequencies will return to H-W expectations after 1 generation of random mating. 3. Consider a population with...

    Consider a locus with two alleles - A and a. These alleles are codominant, meaning that the fitness of the heterozygote is halfway between either homozygote. Consider further a population of randomly mating green frogs where the genotype counts are AA = 500, Aa = 250, and aa = 250. In this population the relative fitnesses of each genotype are AA = 1.00, Aa = 0.80, and aa = 0.60. What is the expected allele frequency change for A after...
