Question

What are the 3 primary sources of genetic variation?

Answer 1

Genetic variation:

1. Genetic variation refers to variations between the genomes of members of the same species.
2. Genes are units of hereditary information.
3. Three primary sources of genetic variation are mutation, genetic recombination, and gene flow in the population.

• Mutation: the changes in the sequences of genes in DNA are known as mutation.
• Gene flow: the transfer of genetic material from one population to another is known as gene flow.
• Genetic combination: sexual reproduction leads to the formation of new combinations of genes called genetic combinations.
