Table 4. Analysis of molecular variance among and within sampled populations of Penicillium marneffei*.

Source	df	Estimated variance (%)	p value
Regions (China and Thailand)	1	0.974 (39)	>0.001
Among species (humans and rats)	2	0.059 (2)	>0.002
Within species	265	1.446 (58)	>0.001
Total	268	2.478 (100)

*%, percentage of the total variance component across the specified hierarchy; p, probability that the observed variance is greater than that expected for the null hypothesis Ho, generated by 999 random permutations of the data.
