Ask EduPadi AI for a detailed answer
Correct Option: A

External fertilization is the process where the fusion of gametes (sperm and egg) occurs outside the body of the female. This is common in aquatic environments where sperm can easily reach the eggs.

  • Toads: Toads are amphibians, and amphibians typically exhibit external fertilization in water. The female toad releases eggs, and the male toad releases sperm, fertilizing the eggs in the surrounding water.
  • Lizards, birds, and cockroaches: These animals are terrestrial and have internal fertilization.
