A) It acts on genotypes rather than phenotypes.

D) It always selects for more complex forms.
E) It always selects for forms that are a mutated variation.

Question

Quizplus · Accepted Answer

Natural selection favors the survival of individuals that possess adaptive characteristics, which usually occur in younger individuals that have not yet reproduced. It acts on phenotypes, or the observable characteristics of an organism, rather than genotypes, or the genetic makeup. It does not assure the survival of every fit individual, as factors such as environmental changes and competition can still result in the death of fit individuals. Natural selection does not always select for more complex forms, as simplicity can be advantageous in certain environments. It does not always select for mutated variations, as beneficial traits can arise through genetic recombination or other mechanisms.
