Phenotypic stasis with genetic divergence [PDF]
Peer Community Journal, 2023 Whether or not genetic divergence in the short-term of tens to hundreds of generations is compatible with phenotypic stasis remains a relatively unexplored problem.

Cropland connectivity affects genetic divergence of Colorado potato beetle along an invasion front
Evolutionary Applications, 2021 The population genetic structure of invasive species can be strongly affected by environmental and landscape barriers to dispersal. Disentangling the relative contributions of these factors to genetic divergence among invading populations is a ...

Genetic divergence of tomato subsamples [PDF]
Revista Ceres, 2014 Understanding the genetic variability of a species is crucial for the progress of a genetic breeding program and requires characterization and evaluation of germplasm. This study aimed to characterize and evaluate 101 tomato subsamples of the Salad group

Urbanization and a green corridor do not impact genetic divergence in common milkweed (Asclepias syriaca L.) [PDF]
Scientific Reports, 2023 Urbanization is altering landscapes globally at an unprecedented rate. While ecological differences between urban and rural environments often promote phenotypic divergence among populations, it is unclear to what degree these trait differences arise ...

Song and genetic divergence within a subspecies of white-crowned sparrow (Zonotrichia leucophrys nuttalli). [PDF]
PLoS ONEAnimal culture evolves alongside genomes, and the two modes of inheritance-culture and genes-interact in myriad ways. For example, stable geographic variation in culture can act as a reproductive barrier, thereby facilitating genetic divergence between ...

Genetic divergence in Brachiaria species
Crop Breeding and Applied Biotechnology, 2002 Three hundred and one accessions of six different Brachiaria species were analyzed, in which twentyfour morphologic characteristics were evaluated. Discriminant analysis based on principal components and Anderson’s discriminant analysis were conducted ...

Genetic divergence in chilli accessions [PDF]
Electronic Journal of Plant Breeding, 2010 A study of genetic diversity in 25 chilli genotypes for various characters revealed substantial differences for all the traits.Based on D2 values, the genotypes were clustered into eight constellations.

Genetic divergence is not the same as phenotypic divergence [PDF]
Molecular Breeding, 2011 Far too often, phenotypic divergence has been misinterpreted as genetic divergence, and based on phenotypic divergence, genetic divergence has been indicated. We have attempted to disprove this statement and call for the differentiation of phenotypic and genotypic variation.

Divergence Population Genetics of Chimpanzees [PDF]
Molecular Biology and Evolution, 2004 The divergence of two subspecies of common chimpanzees (Pan troglodytes troglodytes and P. t. verus) and the bonobo (P. paniscus) was studied using a recently developed method for analyzing population divergence. Under the isolation with migration model, the posterior probability distributions of divergence time, migration rates, and effective ...
