Examples of fitnessfitness The relative fitnesses are also scaled by the arbitrary assumption of a generation time l 15 days made when fitting the discrete model. If the wild-type homozygote is viable and fertile, then it is impossible to infer the four fitnesses from the three chromosome frequencies alone. 346 sume the one-locus model of fitnesses given above. However, locally stable polymorphisms are possible even if all double homozygotes have higher geometric mean fitnesses than all other genotypes. If so, then mean fitnesses do not climb peaks in the adaptive topography. The fitnesses of the heterozygotes and homozygotes for the disfavoured allele are 1khs and 1ks, respectively. Offspring phenotypes and fitnesses are assigned as above. Also, relative fitnesses might change through time, as a result of direct or indirect frequency-dependence. When this is so, the interactions between the loci in fitnesses will be at least of the same order of magnitude as their individual effects. Their results indicated that genetic background did not have a strong consistent effect on the adaptive evolution they studied; allelic fitnesses were not strongly dependent upon genetic background. The numbers and effects of the mutations can then be estimated from the fitnesses of the replicates by means of a model of the mutational effects. Dynamical behavior for population genetics models of differential and difference equations with nonmonotone fitnesses. A straightforward, pragmatic solution is to allocate fitnesses and transmission rate parameters directly to combinations of genotypes and cultural traits, a package known as a phenogenotype. The coevolution approach reformulates the given or intrinsic fitnesses by formulating extrinsic fitnesses that take into account a component's contribution to the assembly that uses it. Note that because the fitnesses of the two hermaphrodite genotypes are identical when l=0, we need only consider the phenotypes involved to determine hermaphrodite invasion criteria.
