Question

In the case of internal fertilisation, the chances of survival of the zygote are more than that in external fertilisation.

• A. zygote
• B. False

Answer 1

The correct option is A zygote

In the case of internal fertilisation, the chances of survival of the zygote are more than external fertilisation. In the case of external fertilization, the male and female gametes are released into the environment (mostly in water) and fertilisation also takes place outside the body of both the parents. Thus, there is a higher chance of the gametes and the zygote getting destroyed by water, wind, heat, predation, etc.
