1) A rabbit warren has 300 individuals. The coat colour of rabbits is expressed through incomplete dominance. The coat colour can be dark brown, light brown, or white.
There are 81 dark brown rabbits, 150 light brown rabbits, and 69 white rabbits. Assume that all of the conditions are met for a population in Hardy–Weinberg equilibrium.
What is the genotype frequency of light brown rabbits, the phenotype frequency of white rabbits, and the dark brown allele frequency?
a. Genotype of Light Brown Rabbits Phenotype of White Rabbits Dark Brown Allele Frequency
0.50 0.23 0.52
b. Genotype of Light Brown Rabbits Phenotype of White Rabbits Dark Brown Allele Frequency
0.27 0.48 0.52
c. Genotype of Light Brown Rabbits Phenotype of White Rabbits Dark Brown Allele Frequency
0.27 0.23 0.77
d. Genotype of Light Brown Rabbits Phenotype of White Rabbits Dark Brown Allele Frequency
0.50 0.48 0.77
2) In mice, albinism (g) is recessive to grey coat colour (G). The fur colour in mice is a single gene trait controlled by two alleles.
In an ideal mouse population exhibiting Hardy–Weinberg equilibrium, a grey mouse mated with an albino mouse. Over the course of several months, 64 pups were born.
If the albino allele has a frequency of 0.375, which of the following rows identifies the number of the grey and albino alleles in the population of 64 pups?
a. Grey Allele Albino Allele
80 48
b. Grey Allele Albino Allele
48 80
c. Grey Allele Albino Allele
40 24
d. Grey Allele Albino Allele
24 40
3) Grey eyes (b) are recessive to brown eyes (B) in rabbits. In an ideal rabbit population exhibiting Hardy–Weinberg equilibrium, if allele b has a frequency of 0.48, what percentage of the population is heterozygous for this trait?
