With all due respect I ask the following.
I carried out AMOVA based on STRUCTURE clustering and got the following results for % variance
Among populations 13%
Among individuals within populations -11%
Within individuals 98%
Total 100%
•What does the negative value in 'Among individuals within populations' (-11%) say?
•If the variation among populations (STRUCTURE clusters) is 13 percent, then how to calculate the variation within populations? -11% + 98% =87% Or do I need to carry out some other calculation?
Sincerely,
Grim

Regarding the variation within populations, I saw some research articles report it like this
Article 1:
"Analysis of molecular variance (AMOVA) identified 4% variance among and 96% variance within subpopulations"
Article 2:
"The AMOVA on the landrace population vs. cultivar population showed a much greater variation within a population (67.36% + 17.08% = 84.44%) than among the populations (15.56%, p < 0.001)"
It seems like they add the 'Among individuals within populations' and 'Within individuals' %. Can you please provide your input as to why they report it like this?
I would suggest for you to post to R-SIG-Genetics about this inquiry because there are people on that list with much more expertise in AMOVA than I (poppr only provides an interface for two different amova functions in the ade4 and pegas packages). I'm afraid I cannot interpret single quotes and table images from random articles without citations or context.
Please place an "x" in all the boxes that apply
