Solution

Genetic diversity is ultimately/mainly the result of mutations.

Here's a step-by-step explanation:

  1. Mutations: These are changes in the DNA sequence of a cell's genome and are the primary source of genetic diversity. They can occur spontaneously during DNA replication or as a result of exposure to radiation or chemicals.

  2. Reproduction: This can contribute to genetic diversity through sexual reproduction, where genes from two parents are combined to create offspring with a unique genetic makeup. However, the primary source of new genetic material is still mutations.

  3. Meiosis: This is a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell. It is involved in sexual reproduction and can contribute to genetic diversity by shuffling the genes during the formation of sperm and egg cells. But again, the new genetic variations arise primarily from mutations.

  4. Viruses: While viruses can introduce new genetic material into the organisms they infect, this is not a primary source of genetic diversity in most species.

So, while reproduction, meiosis, and viruses can all contribute to genetic diversity, the main source is mutations.
