From: The association of mitochondrial DNA haplotypes and phenotypic traits in pigs
Assessment of phenotypic traits relative to mtDNA haplotype for males where sires were restricted to females from one mtDNA haplotype only at joining. 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
