4 Genetic material contained in pairs of human
chromosomes determine whether a child
is male or female. Males have the pair XY
chromosomes and females XX. Inheriting the
XY combination causes male characteristics to
develop and XX causes female characteristics
to develop. Sperm contain an X or Y with
equal probability and an egg always contains
an X. An infant inherits one chromosome
determining gender from each parent.
a Complete the following Punnet square to
show the possible outcomes of pairs of
chromosomes that can be inherited:
Chromosome inherited from mother
XX
