Number and mode of inheritance of QTL influencing backfat thickness on SSC2p in Sino-European pig pedigrees [PDF]
Background In the pig, multiple QTL associated with growth and fatness traits have been mapped to chromosome 2 (SSC2) and among these, at least one shows paternal expression due to the IGF2-intron3-G3072A substitution. Previously published results on the

Composite Interval Mapping Based on Lattice Design for Error Control May Increase Power of Quantitative Trait Locus Detection. [PDF]
Experimental error control is very important in quantitative trait locus (QTL) mapping. Although numerous statistical methods have been developed for QTL mapping, a QTL detection model based on an appropriate experimental design that emphasizes error ...

Quantitative Trait Loci Affecting Milk Production Traits in Finnish Ayrshire Dairy Cattle [PDF]
A whole genome scan of Finnish Ayrshire was conducted tomap quantitative trait loci (QTL) affecting milk production. The analysis included 12 half-sib families containing a total of 494 bulls in a granddaughter design.

Quantitative trait loci for bone traits segregating independently of those for growth in an F-2 broiler X layer cross [PDF]
An F-2 broiler-layer cross was phenotyped for 18 skeletal traits at 6, 7 and 9 weeks of age and genotyped with 120 microsatellite markers. Interval mapping identified 61 suggestive and significant QTL on 16 of the 25 linkage groups for 16 traits.

The Power of QTL Mapping with RILs
QTL (quantitative trait loci) mapping is commonly used to identify genetic regions responsible to important phenotype variation. A common strategy of QTL mapping is to use recombinant inbred lines (RILs), which are usually established by several generations of inbreeding of an F1 population (usually up to F6 or F7 populations).

A Bayesian approach to detect QTL affecting a simulated binary and quatitative trait [PDF]
Background - We analyzed simulated data from the 14th QTL-MAS workshop using a Bayesian approach implemented in the program iBay. The data contained individuals genotypes for 10,031 SNPs and phenotyped for a quantitative and a binary trait. Results - For
