We present an overview of pedigree-based variance component linkage methods and discuss their extension to oligogenic inheritance. As an example, oligogenic linkage analyses were performed using the quantitative trait Q4 from the GAW10 simulated data set. A strategy involving sequential oligogenic a

โฆ Synopsis
Complete multipoint analysis as implemented by MAPMAKER/SIBS was used to identify the chromosomal regions with the strongest evidence of linkage. Three different quantitative sib-pair methods were compared. For each trait the maximum lod/Z score was used to implicate a chromosomal region. For trait Q5, chromosome 5, the analysis was repeated in a second data set to test for replication of the result from the first data set. The initial screen was carried out using complete parental information and the first sibling pair from each nuclear family. The effect of removing the parental genotypes and the use of multiple independent sibs was examined in the second data set for Q5, chromosome 5.

The multipoint identity-by-descent method (MIM) was extended to test for evidence of quantitative trait loci in two independent genetic regions. This method is a fast and feasible implementation of a multiple-marker, two-region linkage analysis for quantitative traits. It tests for significant evide

Genotype-by-sex (G ร S) interaction refers to the interaction of autosomal genes with male or female physiological "environments." G ร S interaction has been demonstrated in quantitative genetic analyses of a variety of traits including serum lipid concentrations and anthropometrics, and the importa
