Hormonal pleiotropy structures genetic covariance [PDF]
Evolution Letters, 2021 AbstractQuantitative genetic theory proposes that phenotypic evolution is shaped by G, the matrix of genetic variances and covariances among traits. In species with separate sexes, the evolution of sexual dimorphism is also shaped by B, the matrix of between-sex genetic variances and covariances. Despite considerable focus on estimating these matrices,

Genetics of Structural Hair Disorders [PDF]
Journal of Investigative Dermatology, 2012 The identification of causative genes carries the promise of new and innovative therapeutic strategies for both inherited and acquired hair disorders. Moreover, the delineation of the relationships between similar phenotypes, resulting from mutations affecting seemingly distinct regulatory pathways, paves the way to improved diagnosis and treatment ...

The genetic structure of Norway [PDF]
European Journal of Human Genetics, 2020 Abstract The aim of the present study was to describe the genetic structure of the Norwegian population using genotypes from 6369 unrelated individuals with detailed information about places of residence. Using standard single marker- and haplotype-based approaches, we report evidence of two regions with distinctive patterns of ...

Isolation by distance in a population of a small land snail Trochoidea geyeri : evidence from direct and indirect methods [PDF]
, 2006 Population structure was estimated in a continuous population of a small land snail (Trochoidea geyeri). Mark-recapture experiments and randomly amplified polymorphic DNA analyses indicate that the population structure can be described by the isolation ...

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.

The Effects of Forest Management Activities on Genetic Diversity of Forest Trees
Indonesian Journal of Social and Environmental Issues, 2021 Genetic diversity helps to survive forest trees in several environmental changes and disease conditions. Different forest management activities such as harvesting, thinning, natural or artificial regeneration, seedlings or coppice forests, fragmentation,

Ecology and Evolution, 2020 Stocking is often used to supplement wild populations that are overexploited or have collapsed, yet it is unclear how this affects the genetic diversity of marine invertebrate populations. During the 1970s, a lobster stock enhancement program was carried

Genetic structure of chimpanzee populations
PLoS Genetics, 2005 Little is known about the history and population structure of our closest living relatives, the chimpanzees, in part because of an extremely poor fossil record. To address this, we report the largest genetic study of the chimpanzees to date, examining 310 microsatellites in 84 common chimpanzees and bonobos. We infer three common chimpanzee populations,
