WebOct 19, 2024 · Division by mitosis occurs in almost all body (somatic) cells. It produces 2 cells that have identical genetic material and the same number of chromosomes as the parent cell. On the other... WebJul 30, 2024 · Mitosis, Meiosis, and Sexual Reproduction As you now know, genetic variation is very important. Genetic variation is introduced in multiple ways, including changes in mitosis, crossing over and random orientation in meiosis, and random fertilization. The video below offers you a nice overview of how each contributes to genetic diversity.

WebSep 4, 2024 · Crossing over also increases genetic variation, because due to the swapping of genetic material during crossing over, the chromatids held together by the centromere are no longer identical. So, when the chromosomes go on to meiosis II and separate, some of the daughter cells receive daughter chromosomes with recombined alleles. WebGenetic variation is introduced in meiosis during crossing over, independent segregation, random fertilisation and mutations. These events create immense genetic variation. …
