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

Consider two genes that are independent, the A gene and the B gene. Each gene has two alleles (A gene: A1 and A2, B gene: B1 and B2). The frequency of A1 allele at the A gene is 0.67 and the frequency of the B2 allele at the B gene is 0.21. What is the probability of an individual in a randomly mating population of having A1A2B1B2 as their genotype? (calculate to 4 decimal places

1. Fixation of Dominant Alleles Start with a population that has a gene with two alleles (A and a) with classical Mendelian dominance that are at equal frequency (p0.5. q 0.5). Assume this first generation is at hardy Weinberg equilibrium. Calculate the genotype frequencies AA- a. Aa b. Now assume some environmental change that makes the recessive phenotype completely unfit (fitness- 0). Calculate the allele frequencies and genotype frequencies in the second generation. (Hint: Your calculations might be easier if...

1. A particular gene in a given population of individuals has two alleles, A and a. The frequency of the A allele equals the frequency of the a allele. What are the expected genotype frequencies, assuming the population is in Hardy-Weinberg equilibrium? AA = 0.5, aa = 0.5 AA = 0.25, Aa = 0.50, aa = 0.25 O A = 0.5, a = 0.5 The answer cannot be determined because the allele frequencies are not provided.

1. Suppose a population of organisms is in Hardy–Weinberg equilibrium. In the population, a gene has two alleles, B and b. If the frequency of B is 0.72 and the frequency of b is 0.28, what are the expected genotype frequencies of BB, Bb, and bb? Calculate each frequency to two decimal places.

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...

Suppose a population of organisms is in Hardy–Weinberg equilibrium with respect to a gene that has two alleles, Y and y. The YY genotype has a frequency of 0.11, the Yy genotype has a frequency of 0.44, and the yy genotype has a frequency of 0.45. Calculate the frequency of each allele to two decimal places. Y allele frequency: y allele frequency:

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...
