Ancient Cytb gene analyses. Relationship of pig Cytb amino acid sequences. (a) Each haplogroup is represented by a circle, with the area of the circle proportional to the haplogroup’s frequency. Different colors indicate samples originating from different regions. The numbers alongside AA changes are the Grantham scores which help classify the conservation levels of AA changes. The number of asterisks highlights the level: non - considered conservative; one - moderately conservative; two - moderately radical and three - radical, respectively. (b) Alignment of AA changes among the 11 AA haplogroups and 21 DNA haplotypes. The AA haplogroups and DNA haplotypes containing ancient pigs are in red font.
