Genetic Distances among Haplogroups (with One Exception^a) in Northwestern Africa ^[Note]

	Genetic Distances among HGs
Haplogroup	1	2+	21	8	9
HG 1	3.40	4.77	4.44	5.9	8.1
HG 2+	9.80	6.67	4.40	4.56	.25
HG 21	7.29	8.95	2.31	6.13	7.76
HG 8	8.60	8.89	8.29	2	9.68
HG 9	10.99	4.78	10.1	11.87	2.38

Note.—Distances below the diagonal of underlined numbers represent the mean number of repeat differences among all pairs of STR haplotypes between two haplogroups. Distances along the diagonal of underlined numbers denote the mean number of repeat differences within haplogroups. Distances above the diagonal of underlined numbers denote genetic distances among hap

^aHG 26, which was found in only one chromosome, was not included in the determination of genetic distances.
