A high degree of genetic variability among individuals of the same species means that these individuals will always appear morphologically different. For example, as all Adélie penguins look alike, this species must have a low degree of genetic variation.

Question

The statement is incorrect. A high degree of genetic variability can actually result in individuals appearing more morphologically different, as different combinations of traits can be expressed. The fact that Adélie penguins appear very similar is likely due to selective pressures in their environment that have led to a uniformity in their phenotypes, but not necessarily a lack of genetic diversity.
