Answer;
Meiosis
The process of meiosis increases genetic variability as it produces gametes for sexual reproduction.
Explanation;
- Meiosis is the type of cell division which occurs in the gonads in which cells divide in two phases to form four daughter cells that contains half the original number of chromosomes, in other words, haploids.
- Meiosis is an important process as it enhances genetic variation among organisms in the production of gametes.
- During the first phase of meiosis, meiosis I, an important process called crossover which ensures genetic variation or hybrid vigor among organisms occurs in prophase I. It occurs when non sister chromatids of the homologous chromosomes join at chiasmata and exchange genetic materials, a process called crossover.
