Answer 1

Answer:

In the XY sex-determination system, the female-provided ovum contributes an X chromosome and the male-provided sperm contributes either an X chromosome or a Y chromosome, resulting in female (XX) or male (XY) offspring, respectively. Hormone levels in the male parent affect the sex ratio of sperm in humans.

Answer 2

Answer:

Sex of the child is simply a matter of chance. If the X chromosome of the male fuses with the X chromosome of female, a daughter is formed and if the Y chromosome of the male fuses with the X chromosome of the female, a son is formed.
