Question

How is the sex of a Baby determined? Explain with diagram.​

Answer 1

Answer:

Sex of child in humans is determined by the type of male haploid gamete that fuses with the female egg. During spermatogenesis, males produce two types of gametes, half of the sperms have an X chromosome and the other half have a Y chromosome. 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 and if the male gamete with the Y chromosome fuses with the female egg, the child will be male.
