Genomic signatures of host-associated divergence and adaptation in a coral-eating snail, Coralliophila violacea (Kiener, 1836). [PDF]
, 2020 The fluid nature of the ocean, combined with planktonic dispersal of marine larvae, lowers physical barriers to gene flow. However, divergence can still occur despite gene flow if strong selection acts on populations occupying different ecological niches.

Genetic and phenotypic divergence in an island bird: isolation by distance, by colonization or by adaptation? [PDF]
, 2014 Discerning the relative roles of adaptive and nonadaptive processes in generating differences among populations and species, as well as how these processes interact, is a fundamental aim in biology.

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 ...

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.

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

An Improved Approximate-Bayesian Model-choice Method for Estimating Shared Evolutionary History [PDF]
, 2014 To understand biological diversification, it is important to account for large-scale processes that affect the evolutionary history of groups of co-distributed populations of organisms.

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.

Genetic divergence in okra (Abelmoschus Esculentus L. Moench.) [PDF]
Electronic Journal of Plant Breeding, 2013 Genetic divergence was studied among 25 okra germplasm lines using Mahalanobis D2 analysis. Analysis of variances for dispersion indicated significant differences among the genotypes and they were grouped into four clusters. The cluster I consisted of 22
