Sample Question #3

The frequency of autosomal alleles K and k in a large population of snails is 0.6 and 0.4. What is the approximate genotypic frequency of the heterozygote Kk if the inbreeding coefficient (F) was 0.3?

a. 0.48

b. 0.34

c. 0.14

d. 0.30

e. 0.24

Answer 1

The genotypic frequencies of the heterozygotes are calculated by the formula,

2pq (1-F) where F is the inbreeding coefficient

= 2(0.6)(0.4) x (1-0.3)

= 0.48 (0.7)

= 0.336

= 0.34
