WebNatural Selection: Natural selection is an evolutionary process in which the best-fit organisms within a particular species to a particular habitat are able to survive longer. WebWe define S as the selection differential that measures the strength of natural selection, R is the difference between the mean trait value of the offspring of the selected individuals (µ 1) and the mean before selection (µ); R = µ - µ 1 ( Fig. 1B, 1C, 1D ). R = h 2 S.
