Question:
How can we say that fish exhibits external fertilisation?
Solution:
Female fish lay eggs in water while male fish releases its sperms in water. Sperms swim and reach the eggs of fish, randomly due to water
currents.When a sperm comes in contact with the viable egg, nuclei of both the cell fuses to form a zygote. This process of fertilisation takes place in
water outside the female body, hence fertilisation is external in fishes.
