Question
The following statements are related to external fertilization. Choose the correct statements: I. The male and female gametes are formed and released simultaneously II. Only a few gametes are released into the medium III. Water is the medium in a majority of organisms exhibiting external fertilization IV. It presents wastage. a. I and V b. II and IV c. III and IV d. I and III
Correct Answer
Option C is the correct answer.
Detailed Explanation
In external fertilization, gametes are typically released into water (III), which is the medium. Many gametes are released (not a few, II is false) to increase chances of fertilization, leading to significant wastage (IV is true). They may not be released simultaneously (I is not always true). So, III and IV are correct.
Hint
Think of fish spawning in water—lots of gametes, many don't make it.
