Table 1 Sources of variation in blood vessel diameter for four major vessels. ANOVA models were run using Family, Environment and Family by Environment interaction as the modelled sources of variation. Critical F values for the given degrees of freedom (DF) and the calculated F values are given for diameters of the Dorsal and Caudal veins and the dorsal and Caudal arteries. Significant F values (p < 0.05) are in bold face and asterisks represent highly significant (p < 0.005) p values.
