Question

How many unique gametes could be produced through independent assortment by an individual with the genotype AaBbCCDdEE?

Answer 1

The answer is B) 8.

There are 5 genes. There are two possibilities for each of the heterozygous genes and only one possibility for each of homozygous genes. So, the possibilities for each gene are:
Aa - 2: A or a;
Bb - 2: B or b;
CC - 1: D;
Dd - 2: D or d;
EE - 1: E.
Genotype AaBbCCDdEE will have
                2 x 2 x 1 x 2 x 1 gametes

Thus, there will be 8 unique gametes produced by an individual with the genotype AaBbCCDdEE
