J:53484

76 polymorphic markers at an average spacing of 27.5 cM were screened in 535 F2 animals from a cross between inbred strains LG/J and SM/J to identify QTLs affecting skull morphology characteristics. The LG/J strain has a larger body size than the SM/J strain. A total of 26 skull morphology QTLs were identified. On mouse Chromosome 1, Skull1 maps to 46 cM - 68 cM with LOD=4.67 at D1Mit7 and Skull2 maps to 104 cM - 134 cM with LOD>3.03 at D1Mit14.
