. What is the main difference between sperms and eggs of humans? Write the importance of this different


Best Answer

Ans. The main difference lies in the difference in the sex chromosome of sperm (male gamete) and egg (female gamete). The main difference between sperms and eggs of humans is that half of the sperms of a male (father) will have X chromosomes and the other half will have Y chromosomes.  All the eggs of female (mother) will have only X chromosomes. Importance .If the father contributes X sex chromosome, at fertilisation through his sperm, the  baby  born  will  be  a  girl.  On the other hand  if  the  father  contributes  a  Y sex chromosome at fertilisation through his sperm, then the baby born will be a boy. Therefore the sperm determines the sex of the child.
