Question

1a) Genotype frequencies in two populations are as follows:

Population 1: AA = 0.1764, AB = 0.4872, BB = 0.3364

Population 2: AA= 0.3969, AB = 0.4662, BB = 0.1369

What are the frequencies of alleles A and B in each population?

b) A population geneticist genotyped 200 individuals in a population of smallmouth bass (the smallmouth

bass is a popular Ontario sportfish), and the following numbers of genotypes were revealed: AA = 50, BB =

18, CC = 8, AB= 60, AC = 40, BC = 24

What are the frequencies of alleles A, B and C?

Answer 1

Ans:

1. a) The frequencies of alleles A and B in population 1 are 0.42 and 0.58 respectively.

The frequencies of alleles A and B in population 2 are 0.63 and 0.37 respectively.

All the calculation are given below-

b) The frequencies of alleles A, B and C are 0.50, 0.30 and 0.20 respectively.
