Question

If selfing starts in a previously randomly mating population composed of 0.50 heterozygotes, what is the frequency of heterozygotes after three generations of selfing

Answer 1

Answer:

So after the third generation of selfing, 0.0625 population will be hetero zygous.

Explanation:

Selfing or in another term self-breeding lead to the loss of heterozygosity which ultimately decreased the genetic variation of any population. Selfing in each successive generation cause the loss of 50% heterozygosity from parental one

if a randomly mating population start selfing with 50% heterozygosity then after three generations following result will be obtained

F1-0.25%

F2-0.125%

F3-0.0625%
