what are two processes that lead to genetic diversity
Gamete Fusion. The third way that sexual reproduction provides greater genetic diversity than asexual reproduction is through the process of fertilization, or gamete fusion. Gametes contain only half the amount of DNA of a normal cell, so two gametes must fuse to form a new cell that will develop into a new organism.amete Fusion.

Meiosis is the process by which most eukaryotic organisms, those with cells having an organized nucleus, produces sex cells, the male and female gametes. Cells normally have two copies of each chromosome, one donated from each parent.uring prophase of meiosis I, the double-chromatid homologous pairs of chromosomes cross over with each other and often exchange chromosome segments. This recombination creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement.
