Dear student
A human being normally has 46 chromosomes (23 pairs). the 23rd chromosome is a gender chromosome which decides the gender of the offspring.
In human beings, the females have two X chromosomes and the males have one X and one Y chromosome. Therefore, the females are XX and the males are XY.
