Question

How many genotypically different types of gametes could be produced by the individual represented by XxYYzz?

Answer 1

Step-by-step explanation:

An individual with the genotype XxYYzz has two copies of each chromosome and two alleles at each locus. Since there are three loci (X, Y, and Z), the individual has a total of 2^3=8 genotypically different types of gametes. These gametes could be represented as follows:

XYZ

XYz

XyZ

Xyz

xYZ

xYz

xyZ

xyz

Therefore, the individual could produce 8 genotypically different types of gametes.
