Evaluate the final stages of oogenesis and fertilisation.
a. The second meiotic division of the secondary oocyte is completed prior to ovulation.
b. The second meiotic division is unequal, resulting in a tiny second polar body and a large haploid ovum (ootid).
c. After fertilisation, the ovum’s haploid nucleus and the sperm’s haploid nucleus fuse to form a diploid zygote.
d. The mature follicle is called the secondary follicle and contains the secondary oocyte.
e. The zona pellucida is a new membrane formed around the secondary oocyte outside the Graafian follicle.
f. Ovulation is the rupture of the Graafian follicle to release the secondary oocyte.
