How many different kinds of gametes will be produced by a plant having the genotype AABbCC ?The number of different kinds of gametes produced $= 2^n$, where $n$ is the number of heterozygous gene pairs.
In the genotype AABbCC, the gene pairs AA and CC are homozygous, and only Bb is heterozygous.
So n = 1.
Number of kinds of gametes $= 2^1 = 2$
The two kinds of gametes are ABC and AbC.
So the plant will produce two different kinds of gametes.
