Select the incorrect statement about external fertilization.a)Organism...
The incorrect statement about external fertilization is:
- Organisms showing external fertilization produce a large number of male gametes only.
This statement is incorrect because in external fertilization, both male and female gametes are released into the external medium, such as water, where fertilization takes place. Therefore, statement 1 is incorrect.
External fertilization is a reproductive strategy where fertilization takes place outside the body of the organism, usually in a water medium. It is true that external fertilization requires synchronization between the release of male and female gametes, and is more uncertain compared to internal fertilization, which occurs inside the body of the organism.
It is also true that external fertilization is common in many fish and amphibian species, but it is not always replaced by internal fertilization in higher organisms. Some higher organisms, such as some reptiles, birds, and monotremes (egg-laying mammals), still use external fertilization as their primary mode of reproduction.
Therefore, the correct answer is option 1: Organisms showing external fertilization produce a large number of male gametes only.
