* Mitosis creates identical copies: Mitosis is a process of cell division that produces two daughter cells genetically identical to the parent cell. Each daughter cell receives an exact copy of the parent cell's DNA.
* No recombination or crossing over: Unlike meiosis (which produces gametes for sexual reproduction), mitosis does not involve genetic recombination or crossing over. This means there's no exchange of genetic material between chromosomes, preventing the creation of new gene combinations.
* Purpose of mitosis: Mitosis is primarily involved in growth, repair, and asexual reproduction. Its purpose is to maintain the genetic integrity of the organism by producing identical cells for these functions.
Where genetic diversity comes from:
Genetic diversity arises primarily from:
* Meiosis: This process involves recombination and crossing over, shuffling genes and creating unique combinations of chromosomes in gametes.
* Mutations: Random changes in DNA sequences can occur during DNA replication, introducing new variations into the genome.
* Sexual reproduction: The combination of genetic material from two parents during fertilization creates a new, unique individual.
In summary: While mitosis is essential for cell division and growth, it doesn't contribute to genetic diversity. Genetic diversity is primarily generated through meiosis, mutations, and sexual reproduction.
