Answer 1

The statement that would least likely be used to describe variation is:

2. Variations that decrease reproductive success are more likely to be passed on.

This statement is incorrect because variations that decrease reproductive success are less likely to be passed on to future generations. In general, variations that are beneficial or neutral are more likely to be passed on, while variations that are detrimental are less likely to be passed on. This is because individuals with beneficial or neutral variations are more likely to survive and reproduce, while individuals with detrimental variations are less likely to survive and reproduce.
