From: Genetic variation in the pleiotropic association between physical activity and body weight in mice
Locations on each of the chromosomes of direct-effect QTLs for the physical activity/weight traits, relationship QTLs that affect the association of the activity traits and weight, and epistatic QTLs involved in interactions with the relationship QTLs. Direct-effect QTLs = circles, relationship QTLs = triangles, epistatic QTL = squares, DS = distance, DU = duration, S = speed, and W = body weight.
