Animals that
sexually reproduce are diploid and produce haploid gametes. Diploid is having two sets of chromosomes or double the haploid number of
chromosomes in the germ cell, with one member of each chromosome pair derived
from the ovum and one from the spermatazoon. While haploid is Having the same
number of sets of chromosomes as a germ cell, or half the diploid number of a
somatic cell. The haploid number (23 in humans) is the normal chromosome complement of germ
cells.
