In a population of rabbits, there are 496 black rabbits and 27 white rabbits. Fur color is determined by a pair of alleles where

Troyanec [42]

Answer:

$0.96$

Explanation:

It is given that

B is the dominant allele which represents the black color

and b is the recessive allele which represents the white fur.

B being dominant will result into black color fur for genotype "Bb"

Given -

Frequency of black fur allele (p) is $0.8$

As per Hardy Weinberg's first law of equilibrium

$p + q = 1\\$

Substituting the value of p in above equation, we get -

$q = 1-p\\q = 1-0.8\\q= 0.2$

q represents the frequency for white fur allele

Frequency of white fur phenotype is

$q^2\\= 0.2^2\\= 0.04$

Frequency of homozygous black fur phenotype (BB) is

$p^2\\= 0.8^2\\= 0.64$

As per Hardy Weinberg's second law of equilibrium -

$p^2 + q^2 + 2pq = 1\\0.64 + 0.04 + 2pq = 1\\2pq = 1 - 0.68\\2pq = 0.32\\$

Combined frequency of homozygous and heterozygous black fur phenotype is

$0.64 + 0.32\\= 0.96$
