Stabilizing selection occurs in the absence of external changes and relatively weak competition. Suppresses the genotypes of individuals with extreme deviations of traits (for example, too large or too small). Maintains the stability of the population and does not contribute to evolution. stabilizing selection is aimed at maintaining existing phenotypes. This form of selection usually works where living conditions remain constant for a long time, for example, in northern latitudes or on the ocean floor.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
