Question

Quizplus · Accepted Answer

Trisomy 21, commonly known as Down syndrome, is caused by an extra copy of the 21st chromosome. This can happen due to a random error in the cell division process that occurs during the formation of the egg or sperm, or it can happen due to a spontaneous error in the early development of the embryo. In either case, the child will receive the extra 21st chromosome from either the mother or the father. So, option C is correct, whereas options A, B, and D are incorrect.
