From: Microarray estimation of genomic inter-strain variability in the genus Ectocarpus (Phaeophyceae)
Distribution of log2-ratios (sample strain/reference strain 1) in the examined strains of Ectocarpus. "Strain 1" designates a reference-reference hybridization of two independent samples of strain 1. The apparent shift of the curve for strain 5 towards positive values is likely to be an artefact caused by the normalization procedure. Probe frequencies were calculated in intervals of 0.2.
