Notes

Mapping and Phenotype information for this QTL, its variants and associated markers

J:87793

Linkage analysis was performed on 552 10-week old male animals from a (M16i x L6)F2 intercross to identify QTLs associated with measurements of growth such as organ weight, growth rate, and adiposity. 63 polymorphic markers spanning the 19 autosomes wereused in the genome scan. Parental strain M16i is a long term selection line for rapid 3- and 6- week weight gain whereas parental strain L6 is a long term selection line for low 6-week body weight. A total of 50 significant QTLs (LOD>3.3) were mapped over 15 chromosomes. More than 25% of loci mapped to mouse Chromosome 2.

On mouse Chromosome 16, spleen weight QTL Splq8 mapped to 3.4 cM (LOD=3.9) between D16Mit55 and D16Mit57 with L6-derived alleles conferring dominantly inherited decrease in spleen weight.
