Sentence examples for be favoured by selection from inspiring English sources

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.

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.

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.

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

Computer modelling has suggested homogenisation would act to reduce mutational load and could therefore be favoured by selection [ 5, 6].

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

Of the processes capable of maintaining variation, negative frequency-dependent selection (where rare types are favoured by selection) is the most powerful, at least in theory1; however, few experimental studies have confirmed that this process operates in nature.

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.

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.
