Comparison of samples using unweighted UniFrac.

<p>Unweighted UniFrac was used to generate a matrix of pairwise distances between communities, then a scatterplot was generated from the matrix of distances using Principal Coordinate Analysis. Number = chicken ID, R = right, L = left, F = femur, T = tibia. A. Comparison of 4 samples from the same chicken, which has FHS on both femurs and THN on both tibias. B. Comparison of the samples from different individual chickens. Paired samples from same individual chickens have FHS on femurs and THN on tibias.
