From: The association of mitochondrial DNA haplotypes and phenotypic traits in pigs
Assessment of phenotypic traits relative to mtDNA haplotype for females where sires were joined to females from more than one mtDNA haplotype. 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
