BMC Evolutionary Biology, 2011 Background Reproductive isolation (RI) is widely accepted as an important "check point" in the diversification process, since it defines irreversible evolutionary trajectories. Much less consensus exists about the processes that might drive RI.

Genetic Divergence of Two Sitobion avenae Biotypes on Barley and Wheat in China
Insects, 2020 Host plant affinity and geographic distance can play critical roles in the genetic divergence of insect herbivores and evolution of insect biotypes, but their relative importance in the divergence of insect populations is still poorly understood. We used

Genetic Progression and Divergence in Pancreatic Carcinoma [PDF]
The American Journal of Pathology, 2000 Genetic alterations of pancreatic intraductal lesions adjacent to invasive ductal carcinoma were investigated. We submitted nine foci of ordinary epithelium, 12 foci of nonpapillary hyperplasia, 12 foci of papillary hyperplasia (pap HP), 66 foci of severe ductal dysplasia, and 27 invasive foci from a total of 10 pancreatic carcinomas for genetic ...

THE RELATIONSHIP OF HETEROSIS AND GENETIC DIVERGENCE IN MAIZE [PDF]
Genetics, 1965 HETEROSIS in maize appears to increase with increased genetic divergence of the parent populations over a rather wide range of diversity (MOLL, SAL- HUANA and ROBINSON 1962). It does not necessarily follow, however, that this relationship will hold throughout the entire ran.ge of diversity in the species.

African Crop Science Journal, 2011 Fifty genotypes of lentil (Lens culnaris Medik) were evaluated under eight environments for seed yield and its associated traits. All the genotypes were grouped into seven clusters. The composition of various clusters variedfrom 2 to 12. Clustering pattern revealed the distribution of the genotypes belonging to the same origin in more than one cluster ...

PLoS ONE, 2016 The Philippine Islands are one of the most biologically diverse archipelagoes in the world. Current taxonomy, however, may underestimate levels of avian diversity and endemism in these islands.

Genetic divergence among pumpkin landraces
Semina: Ciências Agrárias, 2016 Estimating the genetic variability in germplasm collections is important not only for conserving genetic resources, but also for plant breeding purposes. However, generating a large number of different categories data (qualitative and quantitative) often

Experiments in genetic divergence for emergent systems [PDF]
Proceedings of the 4th International Workshop on Genetic Improvement Workshop, 2018 Emergent software systems take a step towards tackling the ever-increasing complexity of modern software, by having systems self-assemble from a library of building blocks, and then continually re-assemble themselves from alternative building blocks to learn which compositions of behaviour work best in each deployment environment.

Genetic divergence disclosing a rapid prehistorical dispersion of Native Americans in Central and South America. [PDF]
PLoS ONE, 2012 An accurate estimate of the divergence time between Native Americans is important for understanding the initial entry and early dispersion of human beings in the New World.
