Question

What occurs when natural selection favors one of the extreme variations of a traits

Answer 1

When natural selection favors one of the extreme variations of a trait, it is known as directional selection. This happens when individuals with the extreme trait variation have a higher fitness and are better adapted to their environment compared to individuals with intermediate trait values. Over time, the extreme trait may become more prevalent in the population as individuals with that trait are more likely to survive and reproduce, passing on their genetic traits to future generations. This can lead to the evolution and adaptation of the population to better suit their environment.
