Body mass at 90 days for rat pups born to either a lean genotype dam (L) or an obese phenotype dam (O) and cross fostered to either a lean or obese genotype dam. L–L = lean–lean; O–L = lean–obese; O–O = obese–obese; L–O = lean–obese. Pup phenotype matched the nursing dam genotype, although O–O males were significantly larger than O–L males.
