Sentence examples for equal fitness from inspiring English sources

In this analysis, the model with variable deleterious fitness effects fits the data much better than one with equal fitness effects (model 2 vs. 1, P < 0.001; table 1).

Equal fitness, however, was no guarantee of success in the field, especially given the much greater number of wild-type mosquitoes.

The heterozygotes and the homozygotes for the normal allele (A1) have equal fitness, higher than that of the homozygotes for the deleterious mutant allele (A2).

In the course of 20 years of hiking, Michael O'Shea, a physicist at Kansas State University, Manhattan, noticed something rather peculiar: Smaller individuals often seemed better able to carry a heavy pack than larger ones of equal fitness.

Individuals of equal fitness but different phenotypic values trace out fitness isoclines in the space.

Recombination can avoid clonal interference, that is, competition between mutations of almost equal fitness increase.

All three genotypes have equal fitnesses when the frequency of the S allele, represented by p, is about 0.70, so that there is a stable polymorphism with frequencies p2 = 0.49 for SS, 2pq = 0.42 for SF, and q2 = 0.09 for FF.

Owing to the multiplicative nature of the group-mean fitness function (a pres [ 13]), many combinations of competition and policing have equal fitnesses.

In contrast, in the case of 4 possible alleles and equal mutation rates, the lowest value of r, attained when two alleles confer equal fitnesses and the other two are strongly deleterious, is only two times lower than its value under selective neutrality.

For nonsynonymous sites, however, it seems likely that many sites with AC in mouse-rat will be only twofold neutral; the amino acids resulting from A or C at that position may have equal fitnesses, but the G or T amino acids may be strongly selected against.

The results were therefore encouraging because they suggested that short-term captive-rearing programs of one generation might be capable of generating fish with quasi-equal fitness to that of wild fish.
