Determining *** of a baby
The *** of baby is depends upon the chromosome.
Chromosomes are thread like structures
Present in human beings as a set of 23 pairs. Two of which are *** chromosomes named X and Y.
A female child has two X chromosomes whereas a male child has one X and one Y chromosome.
The male and female gamates have only one set of chromosomes.
An unfertilised egg has one X chromosome.
But different sperms carry different chromosome i.e. X as well as Y.
If a sperm containig X chromosome fertilises the egg then the resulting fertilised egg contains two X chromosomes that will give birth to a baby girl whreas if a sperm containing Y chromosome fertilises the egg then the resulting egg contains one X and one Y chromosome that gives birth to a baby boy.
