Question
Zygotes formed by internal fertilisation have better chance of survival than the ones formed by external fertilisation.
Answer: Option A
:
A
Ininternal fertilisation, the survival chancesof the zygote are more than external fertilisation. In external fertilisation, the male and female gametes are released into the environment (mostly in water) and fertilisation takes place outside the body of both the parents. Thus, there is a higher chance of the gametes and the zygote getting destroyed by agents like water, wind, heat andpredators.
