We speculate that their identification in our analysis suggests that sun exposure may have shaped (Neanderthal DNA), and that
gene flow into modern humans continues to contribute to variation in these traits today," according to Janet Kelso, of the Max Planck Institute for Evolutionary Anthropology in Germany, and colleagues.
html) report on the research, the team constructed a model of this mating and
gene flow to observe how it may have happened.
Synopsis: The dispersal of pollen and spores by wind is central to some of the biggest challenges in agricultural science today, such as the spread of food-supply-threatening plant diseases; the rapid and widespread adoption of genetically modified (GM) plants in agriculture and their potential for pollen-mediated
gene flow in the environment; and the presence and role of bioaerosols in cloud processes.
This unusual life cycle, with small local populations, overlapping generations, and discontinuous distribution, raises interesting questions about levels of genetic differentiation and short- and long-distance
gene flow via animal and wind dispersal among different potholes.
The
gene flow among crops and relative weeds is a threat that has been underestimated in several situations (WARWICK et al.
Furthermore,
gene flow between both social forms is thought to be unidirectional and limited to males from monogyne colonies mating with polygyne queens (Ross 1992; Shoemaker & Ross 1996; Ross et al.
Objective: Speciation is a central process in evolution that involves the origin of barriers to
gene flow between populations.
We focus on 1) general inferences about biogeography and biogeographic history, 2) patterns of
gene flow and isolation upon secondary contact and hybridization, and 3) quantifying levels of genomic divergence between closely related taxa.
Niche-models show that variation among subspecies is likely to reflect adaptation to local conditions coupled with current limitations to
gene flow across ecotones and that birds are likely to have expanded from a refugium in the southwestern United States.
The current study was conducted to demonstrate the genetic variability,
gene flow and rate of migration in mosquito populations between rural and urban areas in Sialkot, Pakistan.
We estimated the
gene flow among six populations of T.
Bayesian analyses employing assignment methodologies uncovered little evidence of contemporary
gene flow between Anchorage and Kenai, suggesting regional isolation.
