All of the gametes in the mother's eggs possess X chromosomes. The father's sperm contains about half X and half Y chromosomes. The sperm are the variable factor in determining the sex of the baby. If the sperm carries an X chromosome, it will combine with the egg's X chromosome to form a female zygote. If the sperm carries a Y chromosome, it will result in a male

Chromosome is present in the nucleus of a cell in the form of chromatin fibre .
Actually these fibre condenses to for, chromosomes during cell division.
These chromosomes has information about the parents ,hence gets passed on to offspring
Every individual has 23pairs of chromosomes out of which one pair is sex chromosomes.
The male has Xand Y .
The female has only x
When X from male fuses with x of female a girl child is born
And if y fuses with x then make baby is born
So this is how chromosomes affect or influence the sex of a child
