Asingle tall, heterozygous tt pea plant and its progeny in subsequent generations are self-fertilised. how many generations would it take to attain approximately 94 percent homozygosity?

a. 2

b. 3

c. 4

d. 5

e. 6

The correct answer is "4"

Explanation:

Selfing or self-fertilization occurs when female and male gametes coming from the same organism originate a new organism. The genetic consequence of self-fertilization is that genetic loci that were heterozygous are eventually displaced to homozygous. In the case that a single heterozygous Tt pea plant have its progeny exclusively by self-fertilization is that for each generation half of the genetic loci that were heterozygous is going to be lost. Therefore in F1: 50% would be heterozygous, in F2: 25%, in F3: 12.5% and by F4, only 6.25% would be heterozygous. Therefore it would take 4 generations to attain approximately 94 percent homozygosity.
