Sentence examples for gene flow back from inspiring English sources

The worldwide pattern of variation at NAT2 individual SNPs and haplotypes is barely compatible with molecular radiation after population dispersals out of Africa, because it would require later abundant gene flow back into Africa.

This is unlikely, as recent studies have proposed recent admixture from non-African to African populations (Wang et al. 2013; Wall et al. 2013), and another (Gallego Llorente et al. 2015) has shown that there is European gene flow back into many regions of Africa.

Para 2: Endosymbiotic gene flow is also backed by comparative genomics, for example plants-cyanobacteria. Para 4: Yes, that is exactly right.

At the same time, gene flow from selected trees back into forests could have negative fitness effects for wild populations.

However, there is clear evidence that gene flow between the subpopulations and even back into the wild rice [19] has resulted in the introgression of genomic segments over the course of the domestication process and, most recently, as part of concerted plant breeding programs.

Taken together, Smith says, the findings mean that natural selection in different environments can offset gene flow and create differences in appearance, even when individuals travel back and forth frequently.

Thus, this diffusion most likely depicts recent on-going gene flow introducing new alleles into each continental nuclear gene pool by back-crossing in the absence of maternal lineage mixing.

However, genetic distances within the metapopulation decreased and assignments back to collection of origin decreased following supplementation, suggesting higher gene flow within the metapopulation and lower genetic drift in subpopulations.

The method is based on an isolation-with-gene-flow model, where a single population back in time splits into two, which are subsequently connected by some gene flow.

The method assumes an isolation-with-gene-flow model, where a single population at some point back in time splits into two, which are subsequently connected by some level of gene flow.

If internal barriers to gene flow do not evolve, individuals from the two parts of the population will freely interbreed if they come back into contact.
