What type of fertilization occurs in frogs and what are its disadvantages?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
Frogs undergo external fertilization, where the female releases eggs into water and the male simultaneously releases sperm to fertilize them. The disadvantages of this method include:
- High gamete wastage: Most eggs and sperm don't successfully unite
- Environmental dependency: Requires water bodies for reproduction
- Vulnerability to predators: Eggs and developing tadpoles are exposed to numerous predators
- No parental protection: Offspring receive minimal care after fertilization
- Weather dependency: Drought or extreme temperatures can destroy eggs
Despite these disadvantages, frogs compensate by producing large numbers of eggs, ensuring sufficient survival rates.
