PETS - AN OVERVIEW

Mitochondrial DNA indicates that almost all modern dogs tumble into one of 4 monophyletic haplogroups that are named haplogroups A, B, C, and D. Many dogs slide inside haplogroup A. The mDNA "molecular clock" indicates that 22,800 YBP the 1st genetic divergence (split) transpired in haplogroup A, causing the lineages A1b and A2. This timing will be
