During interphase, the genetic material is duplicated.
Meiosis in reproductive organs (testes and ovary) produce gametes. Each human cell including reproductive cells contains 23 pair of chromosomes. Meiosis separates the two chromosomes from each pair thus, each gamete receives only one copy of each chromosome. Therefore, each gamete has 23 new chromosomes, one from each of the 23 pairs. During meiosis, exchange of chromosome segment between copies of a pair of chromosomes. The exchange of chromosome segments creates new combinations of genes which enhances genetic variability within a species.

What do u need help with?.
Explanation:
<span>Sexual reproduction is the most advantageous type of reproduction for the production of a wide variety of organisms because it combines the genetic material of two organisms that mate. Each of the parents contributes half of the offspring's genetic set by creating haploid gametes. The advantage of sexual reproduction is genetic recombination which occurs during the meiosis (formation of gametes).</span>
