Question

Which of the following is not true about external fertilization?

• A. Organisms exhibiting external fertilisation show poor synchrony between the sexes
• B. Organisms exhibiting external fertilization release a large number of gametes into the surrounding medium
• C. Large number of offspring are produced
• D. Offspring are extremely vulnerable to predators

Answer 1

The correct option is A Organisms exhibiting external fertilisation show poor synchrony between the sexes

The organisms exhibiting external fertilization show great synchrony between the sexes in order to increase the chances of syngamy. Such organisms often release a large number of gametes into their surroundings and a large number of offspring are produced. However, as the development is not inside the body of the parent and occurs in the external environment, the offspring are extremely vulnerable to predators.
