Genetic diversity
Explanation:
Sexual reproductions, mutation, and crossing-over generates a wide range of genetic diversity within a population.
- Sexual reproduction is a type of reproduction in which gametes fuses to produce a fertile and viable offspring.
- Mutation is the process of altering genetic sequences in population to production new breeds called mutants.
- Crossing-over is the exchange of chromosomes between two homologous pairs.
All these processes ensures that a pool of diverse gene exists within a population in order give competitive and adaptability advantage to organisms.
