5 SIMPLE TECHNIQUES FOR PET

Mitochondrial DNA suggests that almost all modern dogs drop into one of four monophyletic haplogroups that happen to be named haplogroups A, B, C, and D. Many dogs slide in just haplogroup A. The mDNA "molecular clock" indicates that 22,800 YBP the primary genetic divergence (break up) transpired in haplogroup A, leading to the lineages A1b and A2.
