Detailed explanation-1: -Biologically male people always inherit their X chromosome from their mother. The X chromosome is about three times larger than the Y chromosome, containing about 900 genes, while the Y chromosome has about 55 genes. Female mammals have two X chromosomes in every cell.
Detailed explanation-2: -A mother always passes an X chromosome onto her offspring, but a father can pass on either an X or a Y chromosome. If he passes on his X chromosome, their baby will be genetically female.
Detailed explanation-3: -The chromosomes that determine the sex of the baby (X and Y chromosomes) are called sex chromosomes. Typically, the mother’s egg contributes an X chromosome, and the father’s sperm provides either an X or a Y chromosome.
Detailed explanation-4: -Females have two X chromosomes, while males have one X and one Y chromosome.
Detailed explanation-5: -One of the sex chromosome is inherited to the offspring by the mother and the other is inherited by the father. The mother (females) have two X chromosomes and the father (males) will have X and Y chromosome.
