A study of X-chromosome traits in pedigrees showing affected
persons and both their parents provides some indication of the
source of the X-chromosome in aneuploid individuals, individuals
with abnormal chromosome numbers due to non-disjunction during
gametogenesis. In one family, unaffected parents produce 4
children: two normal females, one normal male and one red-green
color blind male. The affected male has an XXY chromosome
constitution. Red-green color blindness is a recessive trait.
Indicate the source of the X-chromosome in this male and diagram
the meiotic event giving rise to the affected male. If possible,
indicate whether the event occurred in meiosis I or meiosis II.
