I hope this helps!
Changes in mitosis, crossing over, random fertilization and random arrangement in meiosis.
<u>Explanation:</u>
Genetic diversity of sexually reproducing organisms are controlled by many factors and they are - changes in mitosis, crossing over, random fertilization and random arrangement in meiosis.
During crossing over, the sister chromatids of homologous chromosome crossover and exchange their genes which leads to recombination eventually causing genetic diversity.
Random fertilization of male and female gametes leads to the formation of zygote having the genetic content of both maternal and paternal gametes causing variation.
Environmental factors also causes some change in with time.
