Assessment of phenotypic traits relative to mtDNA haplotype for all females investigated. Graphs represent mean ± SEM values for (a) fat density; (b) muscle depth; (c) fat to leanness ratios; (d) lifetime daily gain; (e) good teat quality; (f) muscle score; (g) front leg score; and (h) rear leg score. * = P < 0.05; ** = P < 0.01; *** = P < 0.001; **** = P < 0.0001
