Effects of genetic and environmental factors on trait network predictions from quantitative trait locus data.
The use of high-throughput genomic techniques to map gene expression quantitative trait loci has spurred the development of path analysis approaches for predicting functional networks linking genes and natural trait variation. The goal of this study was to test whether potentially confounding factors, including effects of common environment and genes not included in path models, affect predicti...
متن کاملChanges in genetic and environmental effects on growth during infancy.
BACKGROUND Accelerated infant growth is a possible explanation for the relation between birth weight and adult diseases. OBJECTIVE The aim of this study was to estimate the heritability of infant growth and to examine whether the genetic contribution changes with increasing or decreasing birth weight and gestational age. DESIGN Growth (change in weight z score) was analyzed in 522 infants f...
متن کاملEnvironmental and Genetic Effects on Pigment-Based vs. Structural Component of Yellow Feather Colouration
BACKGROUND Carotenoid plumage is of widespread use in bird communication. Carotenoid-based feather colouration has recently been shown to be dependent on both pigment concentration and feather structure. If these two components are determined differently, one plumage patch may potentially convey different aspects of individual quality. METHODOLOGY/PRINCIPAL FINDINGS We evaluated the effects o...
متن کاملGenetic and environmental effects on the covariation between colour polymorphism and a life-history trait
Variation in coloration with a strong underlying genetic basis is frequently found within animal populations but little is known about its function. Covariation between colour polymorphism and life-history traits can arise because morphs perform differently among environments or because they possess alternative alleles coding for key life-history traits. To test these two hypotheses, we studied...
متن کاملon translation of politeness strategies in dialogues involving female characters in translations and retranslations of novels translated before and after the islamic revolution of iran and their effects on the image of women: a polysystem theory approach
abstract reception environment has considerable effects on accepting a translation. as the expectations of a target culture and its values and needs change throughout history, its criteria for accepting a translation or rejecting it will change accordingly (gentzler, 2001). the expectations of iran, as the reception environment in the present study, have changed after the islamic revolution. i...
