Question

What is sex determination?​

Answer 1

Answer:

A sex-determination system is a biological system that determines the development of sexual characteristics in an organism. Most organisms that create their offspring using sexual reproduction have two sexes. Occasionally, there are hermaphrodites in place of one or both sexes.

Answer 2

Hey!!

Here is your answer -

• Sex determination is a mechanism which determines the individual to be a male or a female based on the sex chromosomes present in it.
• Sex chromosomes in sperms determine the babys gender. Humans have 23 pairs of chromosomes in each cell. A pair of chromosome forms the sex chromosomes. Males carry XY and females carry XX chromosomes. Reproductive cells give rise to gametes by the division of meiosis. A gamete is a mature reproductive cell - a sperm or an ovum.
• If a sperm carrying X fertilises the ovum with X chromosome, then the resulting baby is a girl.
• If a sperm carrying Y chromosome fertilises the ovum with X chromosome, then the resulting baby is a boy.
• Hence, males are responsible for the gender of the newly formed babies.
