Sentence examples for may experience selection from inspiring English sources
Because local placement of masses is likely to profoundly affect O2 supply to embryos, adults, especially adults in temperate and tropical waters, may experience selection for depositing masses in high-flow conditions; the importance of site choice relative to flow has been demonstrated in fish that lay very large, non-gelatinous masses [24].
Even nonsessile animals may experience selection via self-thinning.
For example, alpine species may experience selection for vastly different metabolic regimes depending on whether they are freeze tolerant or freeze avoidant [ 43].
Further, genes that are female-biased in expression may not experience selection exclusively in females.
By using the maximum likelihood method to detect positive selection, we identified gene MSB2 may experience positive selection (LRT = 35.72, p < 0.001).
Loci that are involved in responses to a variety of pathogens may experience balancing selection as a result of diverging selection pressures acting simultaneously on genes which may result in the maintenance of polymorphism [ 32].
Given that some patients harbour a mixture of positively and negatively selected components, the subpopulations defined by components may experience different selection pressures, accounting for the frequency shifts observed during intra-host evolution in some patients [ 5].
Such genes may experience strong selection constraints and consequently exhibit little variation at the nucleotide level.
Williams' [9] theory of antagonistic pleiotropy describes how pleiotropic alleles that increase fitness early in life may experience positive selection even though they incur a fitness cost later in life.
Also, some rare SNPs with ancestral minor alleles may experience positive selection in human evolution.
Parasite diversity on islands may be lower than on the mainland [ 33], so island populations may experience reduced selection pressure, resulting in less MHC variation being maintained [ 34].
