When biotic conditions change among populations or lineages, this underlying mechanism can continue, leading to diversifying selection among species for different alleles or suites of alleles.
Another limitation of the study is the relatively low response rate among controls, possibly leading to selection bias.
I'm leading the selection committee for the Media Lab's Disobedience Award.
Her repertory includes traditional songs alongside selections from from leading Brazilian songwriters, among them Chico Buarque, Djavan and Ary Barroso.
The dog has undergone some of the most extreme directional selection among domesticated animals, leading to the most phenotypically diverse mammalian species on the planet.
This requirement must be also fulfilled by the leading nodes among themselves; therefore, it is an important criterion for the selection of a leading node within a simple cube.
This scenario favours extreme phenotypes that dissipate density-dependent selection regimes leading to resource partitioning among groups and, if these traits are also related to reproductive isolation, to resource based ecological speciation [ 11, 12, 19, 20].
Decision making can be regarded as the outcome of cognitive processes leading to the selection of a course of action among several alternatives.
A spontaneous mutation in ZAP-70, which uncouples membrane proximal TCR signal transduction, impairs thymic selection leading to a peripheral repertoire of autoreactive T cells, which, among other tissues, targets synovial joints manifesting as a symmetrical and destructive polyarthritis.
Further, in young systems such as in the Lesjaskogsvatnet grayling system gene flow and drift may vary in strength, leading to large among year variation in strength of selection [ 34].
Thus despite the apparent loss of functionality across the wAnaITG genome, some paralogs among the multiple wAnaITG copies could be under positive selection leading to the observed pattern of spreading across multiple D. ananassae populations.
