Fig. 1.
Ideograms of genomic imbalance in 85 colorectal tumours comprising low-grade adenoma, high-grade adenoma or intramucosal adenocarcinoma. Chromosomes are ordered from 1 to 22. The coloured horizontal lines represent the frequencies of gains, loss of heterozygosity (LOH) and copy-neutral LOH (CNLOH). Lines on the left indicate losses (red LOH; grey CNLOH), and lines on the right (green) indicate gains
