Day 68: Genetic Landscape (5/27/2008)

I've been playing around with this program that creates "genetic landscapes". This picture shows a 3D plot of 16 populations (unnamed for certain reasons) plotted on the XY axis and the residuals of a regression of pairwise differences on the Z axis. populations that appear above the plane display higher differentiation than expected while those below the plane display a closer than expected genetic similarity.
