Answer» is not responsible for the gender of the babyExplanation: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. |
