WebThe equation uses a covariance between a trait and fitness, to give a mathematical description of evolution and natural selection. It provides a way to understand the effects that gene transmission and natural selection have on the frequency of alleles within each new generation of a population. WebWe can divide the number of copies of each allele by the total number of copies to get the allele frequency. By convention, when there are just two alleles for a gene in a population, their frequencies are given the symbols p p and q q: p = \text {frequency of}\: W p = frequency ofW = = 13/18 13/18 = = 0.72 0.72, or 72\% 72%.
Fitness (often denoted $${\displaystyle w}$$ or ω in population genetics models) is the quantitative representation of individual reproductive success. It is also equal to the average contribution to the gene pool of the next generation, made by the same individuals of the specified genotype or phenotype. Fitness can be … See more Fitness is often defined as a propensity or probability, rather than the actual number of offspring. For example, according to Maynard Smith, "Fitness is a property, not of an individual, but of a class of individuals—for … See more In order to avoid the complications of sex and recombination, the concept of fitness is restricted to an asexual population without genetic recombination. Thus, fitnesses can be … See more Genetic load measures the average fitness of a population of individuals, relative either to a theoretical genotype of optimal fitness, or relative … See more • Sober, E.

WebFor example, a female lion with a well-nourished cub gains inclusive fitness by nursing a starving cub of a full sister because the benefit to her sister ( B = one offspring that would otherwise die) more than compensates for the loss to herself (ℂ = approximately one quarter of an offspring), since the survival probability of her own non-starvi...
