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.
