Sex-linked genetic diversity originates from persistent sociocultural processes at microgeographic scales [PDF]

open access: yesRoyal Society Open Science, 2019
Population genetics has been successful at identifying the relationships between human groups and their interconnected histories. However, the link between genetic demography inferred at large scales and the individual human behaviours that ultimately ...

The dimensions of personality in humans and other animals: A comparative and evolutionary perspective [PDF]

open access: yes, 2000
This paper considers the structure and proximate mechanisms of personality in humans and other animals. Significant similarities were found between personality structures and mechanisms across species in at least two broad traits: Extraversion and ...

Critical mutation rate has an exponential dependence on population size in haploid and diploid populations [PDF]

open access: yes, 2013
Understanding the effect of population size on the key parameters of evolution is particularly important for populations nearing extinction. There are evolutionary pressures to evolve sequences that are both fit and robust.

Missense BICD2 variants in fetuses with congenital arthrogryposis and pterygia

open access: yesHuman Genome Variation
Type 2 spinal muscular atrophy with lower extremity dominance (SMALED2) is caused by bicaudal D cargo adaptor 2 (BICD2) variants. However, the SMALED2 genotype and phenotype correlation have not been thoroughly characterized.

Genetic correlations of fighting ability with somatic cells and longevity in cattle

open access: yesAnimal, 2020
The success in competitions may be stressful for animals and costly in terms of immune functions and longevity. Focusing on Aosta Chestnut and Aosta Black Pied cattle, selected for their fighting ability in traditional competitions, this study ...

Impact of single nucleotide polymorphisms in leptin, leptin receptor, growth hormone receptor, and diacylglycerol acyltransferase (DGAT1) gene loci on milk production, feed, and body energy traits of UK dairy cows [PDF]

open access: yes, 2008
The impact of 9 single nucleotide polymorphisms (SNP) in the leptin (LEP), leptin receptor (LEPR), growth hormone receptor (GHR), and diacylglycerol acyltransferase (DGAT1) gene loci on daily milk production, feed intake, and feed conversion, and weekly ...

A new mapping method for quantitative trait loci of silkworm

open access: yesBMC Genetics, 2011
Background Silkworm is the basis of sericultural industry and the model organism in insect genetics study. Mapping quantitative trait loci (QTLs) underlying economically important traits of silkworm is of high significance for promoting the silkworm ...

Genetic Dominance & Cellular Processes

open access: yesThe American Biology Teacher, 2014
In learning genetics, many students misunderstand and misinterpret what “dominance” means. Understanding is easier if students realize that dominance is not a mechanism, but rather a consequence of underlying cellular processes. For example, metabolic pathways are often little affected by changes in enzyme concentration.

Host-specific functional significance of Caenorhabditis gut commensals

open access: yesFrontiers in Microbiology, 2016
The gut microbiota is an important contributor to host health and fitness. Given its importance, microbiota composition should not be left to chance. However, what determines this composition is far from clear, with results supporting contributions of ...
