Question

why is meiosis important?
all of these are correct.
meiosis contributes to genetic diversity.
meiosis plays an important role in reproduction in many living things.
meiosis creates unique combinations of genes that would otherwise not be possible.

Explanation:

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in the formation of gametes (sex cells). It contributes to genetic diversity through processes like crossing - over and independent assortment. In sexual reproduction, gametes are essential, and meiosis plays a crucial role in their formation. Also, the unique combinations of genes created during meiosis (due to crossing - over and independent assortment) lead to offspring with genetic variations that would not be possible with simple mitotic division.

Answer:

A. All of these are correct.
