Interactions among loci or between genes and environmental factors make a substantial
contribution to variation in complex traits such as disease susceptibility. Nonetheless, many …

The ability of a population to respond to natural or artificial selection pressures is determined
by the genetic architecture of the selected trait. It is now widely acknowledged that a …

Quantitative genetics traces its roots back through more than a century of theory, largely
formed in the absence of directly observable genotype data, and has remained essentially …

Domestic animals are excellent models for genetic studies of phenotypic evolution 1 , 2 , 3 .
They have evolved genetic adaptations to a new environment, the farm, and have been …

The domestic pig originates from the Eurasian wild boar (Sus scrofa). We have sequenced
mitochondrial DNA and nuclear genes from wild and domestic pigs from Asia and Europe. …

Domestication of wild boar (Sus scrofa) and subsequent selection have resulted in dramatic
phenotypic changes in domestic pigs for a number of traits, including behavior, body …

Fig. 1 Test statistic curves obtained in QTL analyses of chromosome 2 in a Wild Boar/Large
White intercross. The graph plots the F ratio in a leastsquares analysis2, testing the …

It is an enigma how long-term selection in model organisms and agricultural species can
lead to marked phenotypic changes without exhausting genetic variation for the selected trait. …

We have identified quantitative trait loci (QTL) explaining a large proportion of the variation in
body weights at different ages and growth between chronological ages in an F 2 intercross …

A large intercross between the domestic White Leghorn chicken and the wild ancestor, the
red junglefowl, has been used in a Quantitative Trait Loci (QTL) study of growth and egg …
