Question

how is sex determined of child in human being

Answer 1

During fertilisation, a sperm having X chromosome or a Y chromosome can fuse with an egg having X chromosome. If a sperm having X chromosome, fuses with an egg (X). The fertilised egg will have XX chromosome. This zygote will develop into a baby girl.

If a sperm having Y chromosome fuses with an egg (X), then the fertilised egg has XY chromosomes. This zygote with XY chromosomes will develop into a baby boy.

Thus, the gender of a child depends on the kind of sperm that fuses with the egg.

The chromosome of the sperm cell from the male parent (father) determines the gender of the child because the egg cell from the mother always has X chromosome.
