Estimates of genetic parameters for physic nut traits based in the germplasm two years evaluation Estimativa de parâmetros genéticos de caracteres de pinhão-manso em dois anos de avaliação do banco de germoplasma

open access: yesCiência Rural, 2012
In spite of increasingly widespread interest in planting physic nut, breeding efforts are still in its infancy. In that context, an important resource recently established aiming future breeding efforts was the assembly of a germplasm bank with near 200 ...

Bigger Is Fitter? Quantitative Genetic Decomposition of Selection Reveals an Adaptive Evolutionary Decline of Body Mass in a Wild Rodent Population

open access: yesbioRxiv, 2016
In natural populations, quantitative trait dynamics often do not appear to follow evolutionary predictions: Despite abundant examples of natural selection acting on heritable traits, conclusive evidence for contemporary adaptive evolution remains rare ...

Genes Software – extended and integrated with the R, Matlab and Selegen

open access: yesActa Scientiarum. Agronomy, 2016
The Genes Software is useful for analyzing and processing phenotypic and molecular data using different biometric models. In the current version we dispose routines to integrate it with three other softwares: the R, Matlab and Selegen.

Spontaneous mutations and the origin and maintenance of quantitative genetic variation

open access: yeseLife, 2016
Mutation and natural selection shape the genetic variation in natural populations. Here, we directly estimated the spontaneous mutation rate by sequencing new Drosophila mutation accumulation lines maintained with minimal natural selection.

A population genetic interpretation of GWAS findings for human quantitative traits [PDF]

open access: yesPLoS Biology, 2017
Human genome-wide association studies (GWASs) are revealing the genetic architecture of anthropomorphic and biomedical traits, i.e., the frequencies and effect sizes of variants that contribute to heritable variation in a trait.

The Autism-Related Protein PX-RICS Mediates GABAergic Synaptic Plasticity in Hippocampal Neurons and Emotional Learning in Mice

open access: yesEBioMedicine, 2018
GABAergic dysfunction underlies many neurodevelopmental and psychiatric disorders. GABAergic synapses exhibit several forms of plasticity at both pre- and postsynaptic levels.

Accounting for genetic differences among unknown parents in microevolutionary studies: how to include genetic groups in quantitative genetic animal models

open access: yesJournal of Animal Ecology, 2016
Summary Quantifying and predicting microevolutionary responses to environmental change requires unbiased estimation of quantitative genetic parameters in wild populations. ‘Animal models’, which utilize pedigree data to separate genetic and environmental

Genetic analysis of quantitative traits in the Japanese population links cell types to complex human diseases

open access: yesNature Genetics, 2018
Clinical measurements can be viewed as useful intermediate phenotypes to promote understanding of complex human diseases. To acquire comprehensive insights into the underlying genetics, here we conducted a genome-wide association study (GWAS) of 58 ...
