Analysis of human diversity data from 30 dinucleotide repeat microsatellites

Population	Average variance	No. of chromosomes	Within-locus (k) test		Interlocus (g) test*		Adjusted P value
			Positive/total	P value	g ratio	P value
N. Central African	7.7	32–38	15/30	P < 0.51	0.32	P < 0.037	P < 0.0007
Zairian	9.1	16–20	15/30	P < 0.51	1.80	—	P < 0.23
European	9.0	34–58	17/30	P < 0.77	3.88	—	P < 0.11
Amerind	8.1	36–60	13/28	P < 0.24	3.08	—	P < 0.40
East Asian	10.0	32–60	18/30	P < 0.87	2.92	—	P < 0.20
Sahulland	9.0	22–40	19/26	P < 0.93	3.33	—	P < 0.10
Melanesian	8.7	14–20	16/23	P < 0.72	2.53	—	P < 0.43

The populations are clustered according to the convention established in earlier literature: “North-Central African” includes Lisongo and Central African Republic Pygmies; “European” includes North Europeans and Italians; “Amerind” includes Karitania, Surui, and Mayan; “East Asian” includes Cambodian, Chinese, and Japanese; and “Sahulland” includes Australian and New Guinean (11). 

^*The g values for the interlocus test are biased high because of variation in the mutation rate. This in turn causes the P values to be biased high, so we only list P values that are significant despite the bias. We also provide a list of adjusted P values that emerge when we drop the exceptionally variable locus D13S122 and correct for variation in the mutation rate.
