An (Awassi � Merino) � Merino backcross family of 172 ewes was used to map quantitative trait loci (QTL) for different milk production traits on a framework map of 200 loci across all autosomes. From five previously proposed mathematical models describing lactation curves, the Wood model was considered the most appropriate due to its simplicity and its ability to determine ...

BackgroundA quantitative and a binary trait for the 14^th QTLMAS 2010 workshop were simulated under a model which combined additive inheritance, epistasis and imprinting. This paper aimed to compare results submitted by the participants of the workshop.MethodsThe results were compared according to three criteria: the success rate (ratio of mapped QTL to ...

... of the observed genotypes corresponding to Kas-1 homozygotes and 49.5% corresponding to Tsu-1 homozygotes. Nonetheless, several genomic regions exhibited significant segregation distortion ... ...

BackgroundRecent developments in sequence databases provide the opportunity to relate the expression pattern of genes to their genomic position, thus creating a transcriptome map. Quantitative trait loci (QTL) are phenotypically-defined chromosomal regions that contribute to allelically variant biological traits, and by overlaying QTL on the transcriptome, ...
