QTL mapping of body-size variants in the domestic dog. (a) Genome-wide single-locus significance for male-average breed body weight across 80 breeds at more than 60,000 markers. The blue dots indicate the -log10 P-values of association for a trait at each marker after controlling for genetic relatedness among breeds. (b) Best-fit regression model using the top six markers explains 72% of the variance of breed-average size among breeds, 72% of the variance of individual body size among breeds, and 25% of the variance of individual body size in village dogs.
