Although growth and body composition traits are quantitative traits of medical and agricultural importance, the genetic and molecular basis of those traits remains elusive. Our previous genome-wide quantitative trait locus (QTL) analyses in an intersubspecific backcross population between C57BL/6JJcl (B6) and wild Mus musculus castaneus mice revealed a major growth QTL (named Pbwg1) on a proxim...

Stereotypic attributions about “overweight people” (called weight stigma or bias) and “slender people” were elicited through semantic differential procedures and compared with self-attributions on the same bipolar personality trait scales. More negative personality traits were attributed to overweight people than to slender people and self-descriptions. Overweight subjects attributed negative t...

IN ACTUALITY, THE DISCIPLINE of functional genomics deals with the science and art of phenotyping. Identifying the genetic bases for complex integrated systems, as well as complex diseases, relies on the validity and accuracy of the “trait measurement.” Any trait, real or erroneous, may be mapped, whether in humans or animal models. Such errors in quantitative trait locus mapping, or even gene ...

The regulation of body weight and composition is complex, simultaneously affected by genetic architecture, the environment, and their interactions. We sought to analyze the complex phenotypic relationships between voluntary exercise, food consumption, and changes in body weight and composition and simultaneously localize quantitative trait loci (QTL) controlling these traits. A large (n = 815) ...

backgounds: a number of studies have focused on the effects of season of birth, as an environmental factor, on embryonic development. methods: in a retrospective descriptive work, heights (crown to heel), weights and head circumferences of the full term, normal, and singleton newborn infants in hamadan city (west of iran) were collected from their randomly selected files in fattemieh hospital d...

Quantitative trait loci (QTL) influencing body weight were mapped by linkage analysis in crosses between a high body weight selected line (DU6) and a control line (DUKs). The two mouse lines differ in body weight by 106% and in abdominal fat weight by 100% at 42 days. They were generated from the same base population and maintained as outbred colonies. Determination of line-specific allele freq...

Production records from 291 Boer-Spanish and Spanish does, collected between 1994 and 2004 in the Edwards Plateau region of West Texas, were examined to compare Boer-Spanish and Spanish does for body weights, fertility, prolificacy, and number of kids weaned. Traits were analyzed using single-trait mixed models. Boer-Spanish does were heavier at birth than Spanish does (2.79 vs. 2.67 kg, P = 0....
