Quizplus · Accepted Answer

Of the 23 pairs of chromosomes in humans, 22 pairs are autosomes (non-sex chromosomes) and one pair consist of sex chromosomes (XX for females, XY for males). Therefore, option C is the correct answer. Option A refers to reproductive cells and option B refers to a type of fertilized egg, which do not accurately describe pairs of chromosomes in the human body. Option D is incorrect because human males have an XY chromosome pair, not a YY pair.
