Sentence examples for differ in fitness from inspiring English sources

As the buzzard colour morphs differ in fitness, we were particularly interested in differences involving transcripts related to melanogenesis.

When genotypes differ in fitness because of their effects on survival, fitness can be measured as the ratio of a genotype's frequency among the adults divided by its frequency among individuals at birth Futuyma (2005) The differential survival and/or reproduction of classes of entities that differ in one or more characteristics.

Initial populations are clonal, but at division, each clone generates mutants at a rate μ that differ in fitness from the parent clone.

First, the two sexes must differ in fitness optima for some phenotype, with a shared genetic basis between males and females.

Finally, as clones differ in fitness under varying environmental conditions [ 6], changes in clone frequencies are expected across the growing season [ 7].

For the most part, WS types arising via the new pathways do not differ in fitness relative to known WS types and therefore their rarity cannot be attributed to a selective disadvantage.

Second, significance of microcosm (random effect, F10,22 = 19.35, p<0.0001) indicates that the small colony phenotypes from different microcosms differed in fitness relative to their respective conspecifics, regardless of their initial frequency.

We did not find any evidence that differences in sex affected the fitness components (Table 4), although sexes differed in fitness-trait performance in S. glauca (Dudley, 2006).

Four cases ("fitness trajectories"), which differ in the fitness of intermediate lineages in the tumorigenic process (Figure 1), are considered for both mutator and non-mutator pathways with respect to the production or birth rate of new malignant lineages.

This approach has allowed us to identify several competing lines carrying different combinations of polymorphic mutations which differ in their fitness values and in their ability to fix when present in a simpler mutant spectrum.
