Explain the importance of meiosis.

(N/A) $\Rightarrow$ Meiosis ensures the conservation of the specific chromosome number of each species across generations in sexually reproducing organisms,even though the process itself paradoxically results in the reduction of the chromosome number by half.
$\Rightarrow$ Meiosis also increases genetic variability in the population of organisms from one generation to the next through the process of crossing over and independent assortment.
