animal reproduction
How creatures multiply
Animal reproduction is the biological process by which animals produce offspring.
It takes two main forms: sexual reproduction, involving the combination of genetic material from two parents, and asexual reproduction, where a single organism produces genetically identical copies.
The term covers everything from mating behaviors and fertilization to gestation and birth: The documentary explored animal reproduction in the deep ocean.
