Mitosis is the process by which a eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets in two nuclei.Meiosis is a special type of cell division
necessary for sexual reproduction. In animals,
meiosis produces gametes like sperm and egg cells,
while in other organisms like fungi it generates spores.
In many organisms, including humans, meiosis begins with one cell containing two copies of each chromosome—one from the organism's mother and one from its
father—and produces four gamete cells containing one copy of each chromosome.
Each of the resulting chromosomes in the gamete cells is a unique mixture of
maternal and paternal DNA, ensuring that offspring are genetically distinct
from either parent. This gives rise to genetic diversity in sexually reproducing populations,
which enables them to adapt during the course of evolution.
