Question

Give scientific reason for the following:

For sexual reproduction, gametes must be produced with haploid chromosomes.

Answer 1

Meiosis:

1. It is a reduction division as it reduces the number of chromosomes to half, hence the gametes produced through meiosis are haploid.
2. This is essential because when the male and female gametes fuse during the process of fertilization, the normal diploid number of chromosomes is regained.
3. To retain the original chromosome number of species, gametes must be produced with haploid chromosomes for sexual reproduction.
