Univariate regression analysis of body weight, length, and adiposity by sex, age, and litter size (N = 457)

Predictor	Trait	% var (r²)^a	β	p
Sex	Body weight	43	−0.65	<0.01
	Body length	24	−0.49	<0.01
	Adiposity	11	−0.34	<0.01
Age	Body weight	0	0.07	0.12
	Body length	3	0.17	<0.01
	Adiposity	2	0.15	<0.01
Litter size	Body weight	2	−0.15	<0.01
	Body length	2	−0.14	<0.01
	Adiposity	2	−0.13	<0.01

Percentage of trait variance accounted for by the predictor. Five mice had missing values for one or more variables and were excluded from the subsequent analysis.
