Selection coefficient w
WebTherefore, the value of the selection coefficient ranges between 0 and 1; the lower the value, the higher the selection against the specific trait. Thus, a phenotype that has a maximum fitness of 1.0, will be experiencing no selection. s = 1 – w. Selection. There are three main types of selections: directional, stabilizing, and disruptive.

WebCoefficient of Selection is a measure of the intensity of this selection force acting against the disadvantageous genotypes in a heterozygous population. Selection against recessives A vast majority of mutations are harmful in nature and when they are recessive they can express only under homozygous conditions and rapidly selected out. WebThe proportional difference from the most fit is called the selection coefficient, s. Hence, s = 1 − w. Alleles carried by less-fit individuals will be gradually lost from the population, and …
WebThis may also be expressed in the form of selection coefficient or 's' which is defined as a force acting on a genotype to reduce its adaptive value. If the adaptive value 'w' is 1, selection coefficient V would be zero or vice versa. … WebTherefore, the value of the selection coefficient ranges between 0 and 1; the lower the value, the higher the selection against the specific trait.
