Phenotypic Selection

Phenotypic selection is a natural process where individuals with certain observable traits are more likely to survive and reproduce. These traits—such as size, color, or strength—affect an organism’s ability to thrive in its environment. Over time, traits that provide advantages become more common in the population, as those individuals pass on their genes. This process drives evolution, shaping the characteristics of species based on which traits improve survival and reproduction chances in a given environment.
