Question:
The primary sex glands that produce the sex cells and manufacture hormones are termed:
a. Gingiva
b. Gonads
c. Gametes
d. Genitalia
Sexual Reproduction:
Sexual reproduction is a type of reproduction that produces offspring through the union of gametes produced by individuals of two different sexes. The offsprings produced in this type of reproduction have high genetic variability which contributes to the richness of diversity in the ecosystem.
