In many species, including humans, females produce eggs and males produce
sperm. Plants also reproduce sexually--the egg and sperm are produced in
the flowers of flowering plants. An egg and sperm unite to begin the development
of a new individual. That new individual receives genetic information from
its mother (via the egg) and its father (via the sperm). Sexually produced
offspring never are identical to either of their parents.
