Question

The following statements and identify the incorrect one(s) related to external fertilisation.

• A. Organisms show great synchrony between sexes and release both the gametes simultaneously.
• B. Not only the male gametes but also female gametes are released in large numbers.
• C. Less number of offsprings are produced as fusion of male and female gametes is a chance.
• D. Offsprings are extremely vulnerable to predators threatening their survival up to adulthood.

Answer 1

The correct option is C

Less number of offsprings are produced as fusion of male and female gametes is a chance.

In external fertilisation, large number of male and female gametes are produced at the same time and released into the surrounding water. As a result large number of offsprings are produced, but they are unprotected and thus extremely vulnerable to predators.
