The gametes that are produced during meiotic divisions are the ones that will be passed on their offspring. Having a mutation on genes that can affect the accuracy of meiosis could potentially increase the occurrence of errors during gamete formation.
Consider the effects of a mutation in humans that reduces the accuracy of the meiotic divisions that give rise to gametes. What predictions can be made about a woman that is homozygous for such a mutation?
A. Most of her children will be boys.
B. Among her children, the frequency of Down's syndrome will be increased compared to the population as a whole.
C. Her children will be taller than average.
D. Among her children, the frequency of XYY male children will be increased compared to the population.
E. Both answers B and D are correct.
