The purpose of meiosis is to produce gametes
and genetic variation. After meiosis, there are
four haploids, each with different sets of
chromosomes. This increases the genetic
variation which allows for evolution and the
adaptation of organisms to different
environments and for sexual reproduction to
occur.

by spindle fibers.
