Detailed explanation-1: -Females have two X chromosomes, while males have one X and one Y chromosome. Early in embryonic development in females, one of the two X chromosomes is randomly and permanently inactivated in cells other than egg cells.
Detailed explanation-2: -There are 2 types of chromosome, called the sex chromosomes, that determine the genetic sex of a baby. These are named either X or Y. Usually, a female baby has 2 X chromosomes (XX) and a male has 1 X and 1 Y (XY).
Detailed explanation-3: -Typically, biologically female individuals have two X chromosomes (XX) while those who are biologically male have one X and one Y chromosome (XY).
Detailed explanation-4: -“Girls born with XY chromosomes are genetically boys but for a variety of reasons – mutations in genes that determine sexual development – the male characteristics are never expressed. They live their lives as girls and then women, and a few can even give birth.
Detailed explanation-5: -Two of the chromosomes (the X and the Y chromosome) determine your sex as male or female when you are born. They are called sex chromosomes: Females have 2 X chromosomes. Males have 1 X and 1 Y chromosome.
