You've got it wrong. Humans have 22 paired chromosomes, plus either an X or Y chromosome, the latter either/or determining the sex of the individual.

Have you ever wondered why our children (except) twins
look so different?  It is because when the mother's egg
is formed, the egg's chromosome is a unique recombination
of the mother's 2 x-chromosones.  Otherwise there would
be only 4 possible chromosome combinations and we could
have pairs of children that were twins, but of different
ages.  If I have got this wrong, please correct me.
