15], but whether these observations apply to empirical data is yet unknown. For example, Edwards [5] did not consider gene flow as an explanation for incongruence; given the ubiquity of gene flow in recent population genomic and phylogenomic studies [16], it could be ...
In the garden experiment a clear picture of actual pollen flow could be shown. Estimates of neighbourhood and gene transport parameters from the data of the three experiments indicated restricted gene flow: neighbourhood size (NJ was between 14 and 20 plants, mean gene transport per generation (M...
In the last chapter, no attempt was made to describe how animals mediate patterns of pollen flow within and between plants, nor how efficient various pollination mechanisms are in the dispersal of pollen and in achieving seed-set. The behaviour of pollinators strongly influences pollen flow, and...
Genetic diversity, genetic structure, and gene flow in plant populations and their influencing factors are important in conservation biology. Cypripedium macranthos is one of the few wild orchids with high ornamental value in northern China. However, over the past decade, excessive collection, trading...
(Fig.1). The specimens dated to 3500–3100 cal. BCE, i.e. several hundred years later than the previously investigated males from Verteba Cave9. The incorporation of these additional data sets obtained from new specimens, sites and time points allows us to draw a more nuanced picture of...
These DEGs indicated differences between MS and LW in endometrial angiogenic regulation at the end of gestation (vascularization, blood flow, perfusion); they suggested less nutrient perfusion from the LW endometrium to the fetus compared to MS, resulting in both lower maturity of their piglets at ...
Theoretical studies have not differentiated between the effects of genes and chromosomal rearrangements on gene flow, but empirical data suggest that there might be a large difference46,47. In three wild sunflower (Helianthus) hybrid zones (Fig. 1a), for example, rates of introgression were 50%...

Overall, the neighbour-joining tree residuals, the haplotype sharing patterns and the many elevatedfb(C) scores paint a consistent picture. They confirm the extensive violations of the bifurcating species tree model initially revealed by theDminanalysis, and suggest many independent gene-flow events at...
Horizontal Gene Transfer (HGT) is beneficial to a cell if the acquired gene confers a useful function, but is detrimental if the gene has no function, if it is incompatible with existing genes, or if it is a selfishly replicating mobile element. If the b
