Question

In external fertilisation, complete development of the embryo takes place ___________.

• A. inside the female body
• B. outside the female body
• C. no embryo formation
• D. inside the male body

Answer 1

The correct option is B

outside the female body

In animals which undergo external fertilisation, development of embryo takes place outside the female body. For e.g., in frogs, both males and females release their gametes in water. Fertilisation takes place in the water, outside the body of both the parents. The development of the embryo also takes place in water.
