Answer 2

Answer:

The presence of XY chromosomes in sperm is what determines gender.

Explanation:

Each cell in a human has 23 pairs of chromosomes, one of which is a pair of sex chromosomes.

• Females have XX and males have XY.

• Females generate a single type of ovum with X chromosomes

• Whereas males create two types of sperm, 50 percent of which have an X chromosome and 50 percent of which have Y chromosomes.

• As a result, it is exclusively determined by the chromosome that the sperm carries at the time of fertilization.

Thus, the sperm determines the child's gender.
