LIFE SCIENCE

Detailed explanation-1: -Typically, biologically female individuals have two X chromosomes (XX) while those who are biologically male have one X and one Y chromosome (XY ). However, there are exceptions to this rule. Biologically female people inherit an X chromosome from their father, and the other X chromosome from their mother.

Detailed explanation-2: -Males have XY sex chromosomes while females have XX sex chromosomes; the male can contribute the X or Y chromosome, while the female must contribute one of their X chromosomes. A male infant results if the male contributes his Y chromosome while a female infant results if he contributes his X chromosome.
