Question:

Define external fertilization. Mention its disadvantages.

Answer:

External fertilization: It means fertilization takes place outside the body.

In external fertilization, eggs have less chances of fertilization. This can lead to the wastage of a large number of eggs produced during the process.

Further, there is an absence of proper parental care to the offspring, which results in a low rate of survival in the progenies.
