Question

Quizplus · Accepted Answer

Down syndrome is caused by an extra copy of chromosome 21, which typically occurs due to a random error during cell division in the egg cell, and the risk of this error increases as the mother's age advances. Therefore, older mothers have a higher chance of having a child with Down syndrome compared to younger mothers.

B) Turner syndrome, C) XYY syndrome, and D) Klinefelter syndrome are not related to the mother's age, but rather result from variations in the sex chromosomes or other genes inherited from either parent.
