Question

13. How is the sex of the child determined in human beings?​

Answer 1

Answer:

Sex of child in humans is determined by the type of male haploid gamete that fuses with the female egg. The chromosome in the 23rd pair of a male gamete can be either X or Y. The female egg always has an X chromosome. So if the male gamete with the X chromosome fuses with the female egg, the child will be female. Similarly if the male gamete with the Y chromosome fuses with the female egg, the child will be male.
