Question

Quizplus · Accepted Answer

The individual can produce 8 different kinds of gametes. This is determined by the heterozygous gene pairs (Bb, Ee, Ff), each of which can produce two types of gametes. Since there are three such pairs, the total number of gamete combinations is 2^3 = 8. The homozygous pairs (AA, CC, dd) do not contribute to the variability in gamete types.
