Skin color in frogs is determined by two alleles of gene B (BB and Bb=brown, bb=green)....

Skin color in frogs is determined by two alleles of gene B (BB and Bb=brown, bb=green). After a drought, 20 frogs remain in the pond. Their genotypes are: 9 BB, 10 Bb, 1 bb. If Hardy-Weinberg equilibrium is established in this new population, what would be the frequency of green frogs in the next generation? A. 0.04 B. 0.09 C. 0.3

Answer #1

Answer:B. 0.09

Explanation:

9 BB, 10 Bb, 1 bb

p^2=9/20=0.45

q^2=1/20 = 0.05

2pq=10 = 10/20 = 0.5

p=0.45+0.25 =0.7

q= 0.05 + 0.25 = 0.3

the frequency of green frogs in the next generation

q^2= 0.3 x 0.3 = 0.09

    2. Alleles D and L are codominant alleles that define fur color in Madagascar lemurs. Lemurs that are homozygous for allele D (genotype DD) have dark brown fur. Lemurs that are homozygous for the L allele (genotype LL) have very light brown fur. The DL heterozygotes are generally light brown, but they have a dark patch or a collar around their neck. Among the 600 Lemurs that you studied on Madagascar, the distribution of genotypes was as follows: Dark brown...

  • 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 =...
