Question

What is meosis? Why do meosis occur in sexual reproduction? ​

Answer 1

Answer:

Organisms that reproduce sexually by joining gametes, a process known as fertilization, must have a mechanism to produce haploid gametes. ... During meiosis, the pairs of chromosomes separate and segregate randomly to produce gametes with one chromosome from each pair.

Answer 2

Answer:

Meiosis, from the Greek word meioun, meaning "to make small," refers to the specialized process by which germ cells divide to produce gametes. Because the chromosome number of a species remains the same from one generation to the next, the chromosome number of germ cells must be reduced by half during meiosis.
