Question

Genetic diversity is measured in terms of allele frequencies (the relative proportions of a specific allele in a gene pool). A population of 3,200 mice has 4,200 dominant G alleles and 2,200 recessive g alleles. What is the frequency of recessive g alleles in the population?

Answer 1

Answer: 0.34375

Step-by-step explanation:

Given : Genetic diversity is measured in terms of allele frequencies .

Allele frequencies : The relative proportions of a specific allele in a gene pool.                                                                                   (1)

A population of 3,200 mice has 4,200 dominant G alleles and 2,200 recessive g alleles.

Combined alleles in gene pool=  4200+2200=6400

Then from (1), the frequency of recessive g alleles in the population will be proportion of recessive g alleles in gene pool  :-

$\dfrac{2200}{6400}=0.34375$

Hence, the frequency of recessive g alleles in the population= 0.34375
