Question

how is sex determine in humans ?? answer it properly

Answer 1

sex is determined by the father's contribution of chromosome if the father contributes Y chromosome the baby will be boy and if the father contribute X chromosome the baby will be a girl

Answer 2

humans have 23 pair of chromosomes out of which 22 are autosomes. and one pair is of sex chromosome.

females have a perfect pair of sex chromosomes (ie- XX), so they will always contribute X chromosome. on the other hand males have a mismatched pair of sex chromosomes (ie- XY).

The sex of the child depends upon the chromosome inherited by his father. An egg fertilised with X chromosome carrying sperm results in a girl child. and if a Y chromosome carrying sperm fuses with egg, male child would born

hope this helps
best of luck for exams ✌
