How do meiotic cell division and fertilization interact to help maintain the species chromosome...

Question:

How do meiotic cell division and fertilization interact to help maintain the species chromosome number?

Meiosis:

Meiosis, compared to mitosis, does not produce daughter cells which are genetically identical to the diploid mother cell. Instead, 4 haploid daughter cells are produced.

Answer and Explanation:

This is important, as only half the normal number of chromosomes of a species are found in a haploid cell. Fertilisation joins two such haploid cells from two different organisms. This not only reestablishes the correct chromosome number of a diploid cell, but also allows for genetic diversity.
