WebMechanisms that generate variation in prokaryote populations. Transduction, transformation, conjugation, transposable elements. Key points: In transformation, a bacterium takes up a piece of DNA floating in its environment. In transduction, DNA is accidentally moved from one bacterium to another by a virus. WebEach resulting cell, or gamete, resulting from meiosis has only half the amount of DNA as the parent cell. So in order to form a new organism, two gametes -- the sex cells, sperm and egg -- must...

WebJul 8, 2024 · How does fertilization generate variation necessary for genetic diversity? Fertilization creates genetic diversity by allowing each parent to randomly contribute a unique set of genes to a zygote. While fertilization is not part of meiosis, it depends on meiosis creating haploid gametes.

WebMeiosis only occurs in reproductive cells, as the goal is to create haploid gametes that will be used in fertilization. Meiosis is important to, but not the same as, sexual reproduction.
