We investigated phylogeographic divergence among populations of Galápagos warble finches. Their broad distribution, lack of phenotypic differentiation and low levels of genetic divergence make warbler finches an appropriate model to study speciation in allopatry. A positive relationship between genetic and geographical distance is expected for island taxa. Warbler finches actually showed a nega...

Parallel patterns of adaptive divergence and speciation are cited as powerful evidence for the role of selection driving these processes. However, it is often not clear whether parallel phenotypic divergence is underlain by parallel genetic changes. Here, we asked about the genetic basis of parallel divergence in the marine snail Littorina saxatilis, which has repeatedly evolved coexisting ecot...

Aegilops tauschii (2n=2x=14), the D-genome donor is closest progenitor to modern wheat representing a large proportion of unexplored genetic variation. Flourishing in adverse climatic conditions it can be utilized improvement programmes. We targeted develop and characterize primary synthetics amphiploids from nine different accessions Ae. one Triticum durum cv. PBW114 through spontaneous chromo...

study of genetic relationships is a prerequisite for plant breeding activities as well as for conservation of genetic resources. since the hybrid canola have more yield than inbred lines, determine the genetic diversity of this have particular importance. in the present study, genetic diversity among 36 genotype of brassica sp. were determined using inter simple sequence repeat (issr) markers. ...

Genetic divergence analysis and combined selection for various physical grain traits are unprecedented commonbean cultivars. The objectives of this study were to examine the genetic variability common bean cultivars 12 graintraits; correlations between these traits; analyze divergence; select superior Twoexperiments carried out in 2019 which 22 different types evaluated. Signifi cant effectsof ...

Gene flow has historically been thought to constrain local adaptation; yet, recent research suggests that populations can diverge despite exchanging genes. Here I use a common garden experiment to assess the combined effects of gene flow and natural selection on morphological variation of 16 wood frog (Rana sylvatica) populations, a species known to experience divergent selection pressures in o...

Landscape genetics holds promise for the forecasting of spatial patterns of genetic diversity based on key environmental features. Yet, the degree to which inferences based on single species can be extended to whole communities is not fully understood. We used a pristine and spatially structured community of three landlocked salmonids (Salvelinus fontinalis, Salmo salar, and Salvelinus alpinus)...
