Men over 40 have a higher risk of fathering a child with autism spectrum disorder than do men under 30 because they have a higher frequency of ________ in their sperm-producing cells.

Question

Quizplus · Accepted Answer

Men over 40 have an increased chance of accumulating random genetic mutations in their sperm-producing cells as a result of ongoing cell divisions over time. These accumulated mutations can increase the risk of fathering a child with autism spectrum disorder. Telomeres and imprints do not directly contribute to the risk of autism spectrum disorder. Teratogens are external agents that can cause birth defects but are not related to this particular risk factor.
