D)contains a set of 23 single unpaired chromosomes

Question

Quizplus · Accepted Answer

The secondary oocyte (also known as the mature oocyte or ovum) contains a half set of doubled chromosomes, which means that it has 23 pairs of chromosomes that have already undergone DNA replication. This is because during meiosis I in females, each primary oocyte divides unequally to produce one secondary oocyte and one polar body. The secondary oocyte then proceeds to meiosis II, where it divides unequally again to produce one mature ovum and another polar body. Only the mature ovum will be fertilized by a sperm cell to form a zygote, which will have a full set of 23 pairs of chromosomes.
