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.
Homework Answers
Answer:
p2 + 2pq + q2 = 1
p= 0.72 (B)
q= 0.28 (b)
Therefore,
(0.72)2 + 2 (0.72) (0.28) + (0.28)2
ƒ(BB)= p2 (0.72)2 = 0.52
ƒ(Bb)= 2pq= 2×(0.72)×(0.28) = 0.40
ƒ(bb)= q2 = (0.28)2 = 0.08
BB= 52%; Bb= 40%; bb= 8%

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:

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.

The frequencies of two alleles in a gene pool are 0.81 (P) and 0.19 (p). Assuming the population is in Hardy-Weinberg equilibrium, what is the frequency of the population that is heterozygous at this gene locus?
Before a drought arrives in the environment, a population of frogs is in Hardy-Weinberg equilibrium
Before a drought arrives in the environment, a population of frogs is in Hardy-Weinberg equilibrium and has a gene that encode for leg length called F, with allele "F" coding for long leg and "f" coding for short leg. Allele frequencies before the drought are: frequency of "F" = 0.7 and frequency of "f" = 0.3. Fitness is measured for each genotype and determined as: fitness of FF = 1, fitness of Ff = 0.4 and fitness of ff =...
Suppose that individuals in a population of annual plants have leaves that are divided into leaflets,...
Suppose that individuals in a population of annual plants have leaves that are divided into leaflets, toothed along the edges, or smooth along the edges. The degree to which the leaves are divided is determined by a single gene with two alleles. The genotype DD results in leaves with smooth edges, the genotype Dd results in leaves with toothed edges, and the genotype dd results in divided leaves. Calculate the genotype frequencies of a population that contains 128 individuals with...
