❓ Frequently Asked Questions
What is animal reproduction?
The biological process by which animals produce offspring and pass genes to the next generation, usually through gametes (sperm and eggs) and fertilization, followed by development.
What are the main modes of reproduction in animals?
Sexual reproduction (involving two parents and fertilization) is most common; asexual reproduction (one individual forms offspring) is rare in animals but occurs in some species.
What is the difference between internal and external fertilization?
Internal fertilization happens inside the female's body (common in mammals, birds, reptiles); external fertilization occurs outside the body, often in water, when eggs and sperm meet there (common in many fishes and amphibians).
What do the terms oviparous, viviparous, and ovoviviparous mean?
Oviparous: lay eggs outside the body. Viviparous: give birth to live young. Ovoviviparous: eggs hatch inside the mother (or shortly after laying) with nourishment from yolk, not a placenta.
