  • There are two pairs of sex chromosomes. One of the sex chromosome is passed on 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.
  • The chromosome which is inherited by the mother will be X.
  • The father can pass on either X or Y chromosome.
  • If the father pass on Y chromosome, the offspring will be male. If the father pass on X chromosome, the offspring will be female.
