Since chemical defences protect amphibians from predators, it seems counter-intuitive that evolving this trait speeds extinction of the lineage.
These estimates, many of them produced by university veterinary schools, measure the degree to which a measurable trait, usually speed, is attributable to the animal's genes.
Using the same set of strains, we also identified npr-1 as the gene contributing to variation in deceleration, consistent with the strong phenotypic correlation of this trait with speed at early time points (Spearman ρ = 0.9, P < 0.0001).
We also found that the tadpole performance traits, swimming speed and acceleration, were not affected by tadpole size, while the froglet performance trait, jump length, was positively correlated with froglet size.
Indeed, those two traits - speed and ability - were too often lacking in NYC FC's play last season, with width also at a premium.
ai decreases as the difference between ui and v increases, which is an appropriate model for trait interactions such as speed–speed, weapon armor, and toxin antitoxin [7].
The speed trait was more favorably expressed in CT heterozygous horses, especially in racing under saddle where the jockey can probably control breaking.
From the various regression patterns exhibited by the relQTLs, it can be predicted that selection for a particular activity trait such as speed would favor different genotypes with different body weights (Additional file 4, Figure 3).
Javier said he and Alou tried to build a team with pitching depth and a lot of speed, traits that are important in a tournament where there is an urgency to prevail in every game.
Still, over the centuries, people have selectively bred types of dogs to emphasize certain traits, including hunting, speed, herding and aggression, said Dr. Katherine Houpt, director of the animal behavior clinic at the Cornell University College of Veterinary Medicine.
