Kavitha gave birth to a female baby.Her family members say that she can give birth to only female babies because of her family history .Is the statement given by her family members true.Justify your answer .

Explanation

No.The statement given by her family members is false.The birth of male or female babies is by random combination of a sperm and egg. Sperms are of two kinds based on sex chromosome (X chromosome & Y chromosome).The eggs always have only X chromosome (sex chromosomes).If a sperm with X chromosome fues with an egg,a girl baby is born.
If a sperm with Y chromosome fuses with an egg,a boy baby is born.The sex of the baby depends on the type of sperm which fertilizers the ovum.'
