Gregor Mendel was an important scientist, considered to be the founder of the science of genetics. His experiments on the crossbreeding of plants and the passing down of favourable traits, led him to establish the laws of Mendelian inheritance. He was using pea plants for his experiments and he was studying seven different pea traits: pea shape and color, pod shape and color, flower color, plant size and position of flowers.

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

$0.64 + 0.32\\= 0.96$
