True
False

Explanation:

Oogenesis gives one large ovum and 3 small polar bodies, each being diploid. Spermatogenesis gives four equal sperm, each being haploid. A homologous pair of chromosomes is the chromosomes which influence the same genetic traits.

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.
