Ever since the integration of Mendelian genetics into evolutionary biology in the early 20th
century, evolutionary geneticists have for the most part treated genes and mutations as …

An understanding of the inheritance of quantitative traits, those with a continuous phenotype,
was first established in the early 1900s. This was instrumental for breeding because …

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

Empirical studies suggest that the effect sizes of individual causal risk alleles underlying
complex genetic diseases are small, with most genotype relative risks in the range of 1.1 …

Host genotype and gender are among the factors that influence the composition of gut
microbiota. We studied the population structure of gut microbiota in two lines of chickens …

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 …

Chicken body weight is an economically important trait and great genetic progress has been
accomplished in genetic selective for body weight. To identify genes and chromosome …

Plant growth and development are tightly linked to primary metabolism and are subject to
natural variation. In order to obtain an insight into the genetic factors controlling biomass and …

Methods for mapping QTL are actively used in the chicken to identify chromosomal regions
contributing to variation in traits related to growth, disease resistance, egg production …

Artificial selection has created myriad breeds of domestic animals, each characterized by
unique phenotypes pertaining to behavior, morphology, physiology, and disease. Most …
