Question

question 3
what are the two main sources of genetic diversity in a population?
mutation and fitness
fitness and adaptation
mutation and sexual reproduction
variation and fitness

Explanation:

Genetic diversity in a population is crucial for evolution and adaptation. Mutation introduces new genetic variations by altering DNA sequences. Sexual reproduction combines genetic material from two parents, creating new gene combinations. Fitness refers to an organism's ability to survive and reproduce, not a source of genetic diversity. Adaptation is a result of natural selection acting on genetic diversity. Variation is a consequence of genetic diversity sources like mutation and sexual reproduction, not a source itself.

Answer:

mutation and sexual reproduction
