Answer:
The most common genotype of a male is XY.
Explanation:
However, sometimes meiosis (the production of gametes, sex cells ie sperm and egg) does not occur as it should and sometimes an egg is fertilized with a sperm that has an xy in it instead of just a y gamete, resulting in a fertilized egg with an xxy geneotype.
Answer: XY is male, and XX is female.
Explanation: males and females have different genes...
