Muscular dystrophy is an X-linked recessive disorder. An
affected XY individual and a homozygous dominant XX individual have
a child who has Klinefelter's syndrome (XXY). If the genotype of
the child contains a copy of the muscular dystrophic allele
and a copy of the wildtype/normal allele for the gene, when during
meiosis did nondisjunction happen, and in which parent was it
caused by? Please show your work by drawing the nondisjunction and
fertilization events for this action.
