Meiosis
In sexually reproducing organisms,
gametes
are produced by
meiosis
, whereas somatic cells are produced by
mitosis
in a sexual reproductive
cycle
.
Meiosis involves two cell
divisions
, each containing a
prophase
,
metaphase
,
anaphase
, and
telophase
.
Unique features of
meiosis
include
synapsis
, homologous
recombination
, and
reduction
division.
