Mother is not responsible for the gender of the baby
Explanation:
- Human females are homogametic, they produce the same types of ova, each having X chromosome.
- While human males are heterogametic, they have 50% sperms with X chromosome while another 50% are with Y chromosome .
- If the sperm having X chromosome fuses with the ovum female foetus is formed, while if sperm with Y chromosome fuses with the ovum , male foetus is formed .
- So, the gender deciding factor is contributed by males and it depends on probability.
