Sentence examples for been favoured by selection from inspiring English sources

Alternatively, mitochondrial introgression could have been favoured by selection, while the nuclear genomes of the two populations were incompatible.

A parent shares half of its genes with each progeny, so a gene that promotes parental altruism is favoured by selection if the behaviour's cost to the parent is less than half of its average benefits to the progeny.

From these expressions for the fitnesses of the two types of organism, we can immediately deduce that the altruistic type will only be favoured by selection if there is a statistical correlation between partners, i.e., if altruists have greater than random chance of being paired with other altruists, and similarly for selfish types.

As pathogens that circumvent the host immune response are favoured by selection, so are host alleles that reduce parasite load.

Thus, hosts are favoured by selection to develop physiological, behavioural or immunological responses to combat parasite pressures [2].

If stronger discrimination were favoured by selection, the prediction based on this finding is more rapid future divergence than if the genes were spread evenly across chromosomes.

Females that do not release a cue decrease the number of matings by producing a gender-neutral trail, and such a strategy would likely be favoured by selection if females are not sperm-limited and if costs of mating are substantial.

Such conflicts are of paramount importance in driving the evolutionary dynamics of herbivore-induced plant signals: when plants sending honest signals are common, there is opportunity for mutants sending dishonest signals and once plants sending dishonest signals become too common, plants sending new-and-honest signals will be favoured by selection.

Male fitness is generally believed to increase with the number of matings, whereas polyandry is favoured by selection under conditions such as depletion of sperm in a female's reproductive tract or indirect genetic benefits via sperm competition or cryptic female choice [1], [2].

These findings indicate that germ plasm might enhance evolvability, which is thought to be favoured by selection (Box 2).

For instance, if female offspring compete for resources required for reproduction, male-biased sex ratios may be favoured by selection.
