Figure 4From: High-depth sequencing of over 750 genes supports linear progression of primary tumors and metastases in most patients with liver-limited metastatic colorectal cancer Allellic imbalance. B-allele frequency plots of heterozygous SNPs in tumor and normal tissue of patients 1 and 2. The y-axis indicates deviation of B-allele frequency from 0.5 towards either 0 or 1; the x-axis indicates chromosomal number.Back to article page
