Wandering behaviour prevents inter and intra oceanic speciation in a coastal pelagic fish [PDF]
, 2017 Small pelagic fishes have the ability to disperse over long distances and may present complex evolutionary histories. Here, Old World Anchovies (OWA) were used as a model system to understand genetic patterns and connectivity of fish between the Atlantic

Genetics of ecological divergence during speciation [PDF]
Nature, 2014 Ecological differences often evolve early in speciation as divergent natural selection drives adaptation to distinct ecological niches, leading ultimately to reproductive isolation. Although this process is a major generator of biodiversity, its genetic basis is still poorly understood.

Genetic divergence studies in safflower (Carthamus tinctorius L.) germplasm lines [PDF]
Electronic Journal of Plant Breeding, 2013 Ninety safflower genotypes representing diverse geographic regions were studied for genetic divergence using Mahalanobis D2 static. The genotypes were grouped into 12 clusters. Seed yield contributed maximum to the total divergence.

GENETIC DIVERGENCE IN DEEPWATER RICE GENOTYPES [PDF]
Journal of Central European Agriculture, 2006 The nature and the magnitude of genetic divergence was estimated in 35 deepwater rice genotypes using Mahalonobis’s D2 – statistics. The genotypes were grouped onto 10 clusters showing fair degree of relationship between geographic distribution and ...

Genetic divergence among genetic groups of Gir crossbreds
Indian Journal of Animal Sciences, 2019 Comparative evaluation of FG (50% HF + 50% Gir), IFG (Interse of FG), FJG (50% HF + 25% Jersey + 25% Gir), IFJG (Interse of FJG) and R (50% HF + 12.50% Jersey + 37.50% Gir) crosses of Gir was done on the basis of age at first conception (AFCon ...

Patterns of reproductive isolation in toads.
PLoS ONE, 2008 Understanding the general features of speciation is an important goal in evolutionary biology, and despite significant progress, several unresolved questions remain.

Estimating genetic divergence and genetic variability with restriction endonucleases. [PDF]
Proceedings of the National Academy of Sciences, 1981 Restriction endonucleases cut DNA at specific sites determined by the local nucleotide sequence. By comparing related DNA segments with respect to where such cuts are made, one can estimate the extent of sequence homology between the segments. Empirical methods are presented here for using these data to measure the proportion of mismatches between two ...

Integrating paleoecology and genetics of bird populations in two sky island archipelagos
BMC Biology, 2008 Background Genetic tests of paleoecological hypotheses have been rare, partly because recent genetic divergence is difficult to detect and time. According to fossil plant data, continuous woodland in the southwestern USA and northern Mexico became ...
