The advantage that internal fertilisation has over external fertilisation is that in internal fertilisation:
(a) new off-springs are exactly like the parent
(b) production of large numbers of gametes is unnecessary
(c) copulation and fusion of gametes is passive
(d) fewer individuals are produced
Correct Answer: (b) Production of large numbers of gametes is unnecessary
Explanation:
The advantage of internal fertilization over external fertilization is that a large number of gametes are not required as internal fertilization provides a safe environment.
