Sexual Selection is type of non-random mating.

Question

BlackTom AI · Accepted Answer

The statement to evaluate is: 'Sexual Selection is type of non-random mating.'

- First, recall the concept: sexual selection is a form of natural selection arising from differential mating success. It specifically involves traits that affect an individual's chances of obtaining a mate (mate choice or competition among members of the same sex).
- This inherently makes sexual selection a non-random process because individuals with certain traits are more likely to reproduce than others, not because of random survival but due to mating advantages.
- Therefore, the main idea is that sexual selection operates through non-random mating decisions and behaviors, such as female choice or male-male competition, rather than random pairing.
- Why this would be considered correct: the emphasis on non-random mating aligns precisely with how sexual selection biases who reproduces, thereby differentiating it from random mating processes.

If a student were to consider why the statement might be mistaken, you could note that:
- Some might confuse sexual selection with general natural selection. While sexual selection is a subset of natural selection, its defining feature is non-random mating based on traits that influence mating success, not just survival.
- Another common pitfall is thinking all mating is random. In fact, many species exhibit strong assortative or competitive mating behaviors that drive sexual selection, supporting the non-random nature.

In summary, because sexual selection depends on mate-related advantages that bias which individuals reproduce, it qualifies as a type of non-random mating.
