Question

In external fertilization, where does the development of 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 male and female release their gametes in water. The fusion of gametes to form zygote takes place in the water, outside the body of both the parents. The development of zygote to offspring also takes place in water.
