Log-ratio and genotype sequences for chromosome 13 in paired samples from a CLL patient. Log-ratio (top) and genotype θ (bottom) sequence for SNPs from chromosome 13 of two samples taken from the same cancer patient: black for normal cell and blue for cancer cell. For the log-ratio plot, the copy number of 2 level log(2/2) = 0 and the copy number of 1 level log(1/2) = -0.693147 are marked.
