Sex determination is the process by which the
sex of an organism is determined. In many
species, the sex of an individual is dictated
by the two sex chromosomes (X and Y) it
receives from its parents. In mammals, some
plants, and a few insects, males are XY, and
females XX; in birds, reptiles, some
amphibians, and butterflies the reverse is
the case. In bees and wasps, males are
produced from unfertilized eggs, females from
fertilized eggs.
