Sentence examples for maintain genetic variation from inspiring English sources

While this is not in itself an evolutionary response, as environmental conditions continue to worsen, heterozygote advantage could help maintain genetic variation, potentially buying time to allow the species to respond via adaptation.

The Red Queen Hypothesis (RQH) predicts that coevolution between hosts and parasites acts to maintain genetic variation through time.

Mating system and gene flow are two mechanisms that allow a population of a species to maintain genetic variation.

Our goal for this exercise is to convey four general concepts (Figure 2a): (1) coevolution occurs rapidly; (2) that which is most fit now can become the least fit in just a few generations; (3) rare advantage, or negative frequency-dependent selection, can maintain genetic variation over time; and (4) we can use simple games to represent complex processes and to test hypotheses.

Environmental and wildlife protection groups such as Citizens for Los Angeles Wildlife have pushed Los Angeles to adopt the plan, saying it will help maintain genetic variation in urban species that might otherwise become isolated, and will reduce conflict with humans by preventing animals from being confined in residential neighborhoods.

Genetic variation in mate preferences may sometimes maintain genetic variation in signals, although the overall selection is usually still directional (but see [35]).

Understanding how biological populations generate and maintain genetic variations that contribute to phenotypic variations is one of the most important issues in evolutionary biology.

This is perhaps the best experimental evidence yet that frequency-dependent selection can be a potent mechanism maintaining genetic variation in natural populations.

They use these data to conduct an independent test of the prediction that host-parasite coevolution maintains genetic variation.

We present the game to the students as a means to test the key prediction of the RQH: host-parasite coevolution maintains genetic variation.

Antagonistic pleiotropy maintains genetic variation across the landscape; however, there is a systematic bias against discovery of antagonistic pleiotropy because the fitness benefits of local alleles need to be significant in at least two environments.
