Answer:
This is in order to maintain the species number of chromosomes.
Explanation:
Reduction division occurs by meiosis and it is very necessary in organisms that reproduce sexually.
Meiosis will take place in the ovary and testis to produce haploid gametes that have half the number of chromosomes compared to the parent cell .
During fertilization the two gametes will fuse to form the offspring an offspring with the same number of chromosomes as the parent. The species number of chromosome has been maintained.
Without meiosis or reduction division the off-springs would have double the chromosomes as the previous generation did.
