Question

Hens and frogs are both oviparous exhibiting different types of fertilisation, explain.

Answer 1

• Organisms that lay eggs are called oviparous. Both hens and frogs are oviparous. However, they exhibit different types of fertilisation.
• In Hens internal fertilisation takes place. The fertilised egg develops inside the female body but the development of chick occurs outside the body.
• On the other hand in frogs both fertilisation and development of zygote to young ones occur outside the body.
