Which of the following does NOT increase genetic variation?Group of answer choicesCrossing OverMutationsGene FlowMitosis

Breakdown the Problem

1. Identify the options provided: Crossing Over, Mutations, Gene Flow, Mitosis.
2. Determine how each process contributes to genetic variation.

Relevant Concepts

1. Crossing Over: A process that occurs during meiosis where two chromosomes exchange genetic material, increasing variation.
2. Mutations: Alterations in DNA sequences that can introduce new traits, thus increasing genetic variation.
3. Gene Flow: The transfer of genetic material between populations, enhancing diversity within a gene pool.
4. Mitosis: A form of cell division that produces two identical daughter cells, thus maintaining the genetic makeup rather than increasing variation.

Analysis and Detail

• Crossing Over contributes to genetic variation by mixing alleles between homologous chromosomes.
• Mutations create new alleles; hence, they are crucial for introducing genetic diversity.
• Gene Flow involves the movement of alleles between populations, directly enhancing genetic variability.
• Mitosis, on the other hand, does not alter the genetic content; it simply replicates the genetic information of the parent cell.

Verify and Summarize

Upon reviewing the definitions and roles of each process related to genetic variation, it is clear that Mitosis does not contribute to genetic variation.

Final Answer

Mitosis does NOT increase genetic variation.
