Detailed explanation-1: -The secondary oocyte remains paused in meiosis II until a sperm cell fertilizes it. This triggers the egg to complete meiosis II. During meiosis II, the duplicated chromosomes are separated into a polar body and a mature ovum. At this point, the haploid nuclei of the egg and sperm are able to fuse to form the zygote.
Detailed explanation-2: -Just one egg is produced from the four haploid cells that result from meiosis.
Detailed explanation-3: -The secondary oocyte enters meiosis II, but is frozen in metaphase II until fertilization occurs. During ovulation, the egg matures further and is released from the ovarian follicles into the oviduct. If it is fertilized by sperm, it finishes meiosis II and becomes an ootid.
