Sentence examples for mating with genetically from inspiring English sources

Material benefits are unlikely in the stickleback system, but polyandry may lower the probability of mating with genetically incompatible, inferior or infertile mates as well as increasing next-generation genetic diversity and mean offspring fitness [ 21, 22].

If genetic differentiation between populations develops, gene flow between populations can introduce traits or alleles which are disadvantageous in the local population and this may lead to organisms within these populations evolving mechanisms that prevent mating with genetically distant populations, eventually resulting in the appearance of new species.

In V. canescens, females use volatile compounds to avoid mating with genetically related individuals [ 40].

If local environmental conditions selectively favour co-adapted ensembles of genes, mating with genetically distant partners could disrupt these assemblages and result in a loss of fitness (outbreeding depression) [ 14- 17].

These results are in agreement with the idea that mating with genetically similar mates can either avoid the disruption of co-adapted genes or confer a benefit in terms of kin selection.

For instance, related individuals might tend to cluster in the same flock, as reported for instance in lekking peacocks (Pavo cristatus) [ 73] and to occupy nearby nest boxes, which might increase the likelihood of mating with genetically similar mates.

The study showed that if wild females preferred to mate with genetically engineered males and if those matings produced offspring that did not survive well, wild populations could be wiped out, a result they called the Trojan gene effect.

Alternatively, the disassortative mating hypothesis [3] states that females should prefer to mate with genetically dissimilar males in order to produce offspring with high levels of heterozygosity.

Our prediction that females would tend to mate with genetically dissimilar mates was based on the assumption that this insular population has low genetic diversity and that it is therefore vulnerable to inbreeding depression.

Contrary to our expectation, we found that offspring were less genetically diverse (multi-locus heterozygosity) than expected under a random mating, suggesting that females tended to mate with genetically similar males.

Overall we found that 29% of litters had multiple sires, but we found no evidence that females were more likely to produce multiple-sired litters when they had the opportunity to mate with genetically dissimilar males compared with controls, regardless of whether females were inbred or outbred.
