Why is meiosis important to sexually reproducing organisms?

Galina-37 [17]

Answer:

Meiosis is important for organisms that reproduce sexually because it is the cell division that serves to obtain gametes or sex cells.

Explanation:

Meiosis is a reductive cell division, involved in the gametogenesis process, where from a diploid cell haploid cells called gametes are obtained.

The gametes, also called sex cells, are responsible for containing the genetic information that each individual will transfer to their offspring.

In sexual reproduction, the importance of gametes is that the paternal and maternal gametes unite in a process called fertilization, to give rise to a diploid cell called a zygote.
