Understanding non-additive effects in the expression of quantitative traits is very important in genotype selection, especially in species where the commercial products are clones or hybrids. The use of molecular markers has allowed the study of non-additive genetic effects on a genomic level, in addition to a better understanding of its importance in quantitative traits. Thus, the purpose of t...

Association mapping has permitted the discovery of major QTL in many species. It can be applied to existing populations and, as a consequence, it is generally necessary to take into account structure and relatedness among individuals in the statistical model to control false positives. We analytically studied power in association studies by computing noncentrality parameter of the tests and its...

A key change in the evolution of our species from a common ancestor with the chimpanzees was the shift to a field of social interaction no longer dependent upon face-to-face interaction for the maintenance of social coherency. Our hunter-gatherers ancestors made a radical shift to social relations based on a culturally constructed system of kinship relations. Unlike biological kinship that refl...

• However, the health of most users of social care services is already damaged and for many this is a central factor in their involvement with social care services. Social work and care interventions targeted at social care clients, and at the general population, can reduce health disadvantage across the life course. • To illustrate this, we chose interventions from across the life course. Stud...

OBJECTIVE Each year more than 500 000 children enter out-of-home placement. Few outcome studies of these children specifically address high-risk sexual behavior and adolescent pregnancy. Our study investigated the relationship between living in kinship or foster care and high-risk reproductive behaviors in a nationally representative sample of women. METHODS Data from 9620 women ages 15 to 44...

BACKGROUND Autosomal and Y chromosome short tandem repeats (STRs) and mitochondrial DNA polymorphisms are the most commonly used molecular tools for determination of kinship. AIM To report a revision of 1,120 kinship cases (paternity and others) analyzed in our laboratory. MATERIAL AND METHODS Revision of all kinship cases analyzed between years 2001-2006. Autosomal and Y chromosome STRs an...
