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

J:59227

Mice were selected for 53 generations for high and low fat content. High (F line) and Low (L line) mice were crossed creating F1 offspring that were mated to produce 436 F2 mice (233 females and 213 males). The F2 mice were genotyped for 71 MIT markers polymorphic in the progenitor strains to identify QTLs that contributed to the fat content phenotype. Fob3 as a QTL showed a significant peak LOD score of 11.3 at an approximate cM position of 34 on mouse Chromosome 15. Fob3 accounted for approximately 14.4 percent of the total fat variance across the F2 population explained by the QTL.
