In our society the women are often blamed for giving birth to daughters. Can you explain why this is not correct?

Text Solution

Verified by Experts

Women are blamed for giving birth to daughters. This is wrong because sex of the baby is determined by the sperm that can have either X or Y-chromosomes. Women have only one type of chromosome (X) in all the ova.
If the sperm having X-chromosome fertilises the ovum (X), the resulting zygote (XX) will become a female.
If the sperm having Y-chromosome fertilises the ovum (X), the resulting zygote (XY) will become a male.
