What Does dogs Mean?
Mitochondrial DNA signifies that nearly all modern day dogs drop into one particular of four monophyletic haplogroups which happen to be named haplogroups A, B, C, and D. Many dogs slide in haplogroup A. The mDNA "molecular clock" indicates that 22,800 YBP the 1st genetic divergence (split) happened in haplogroup A, causing the lineages A1b and A2.
