Chromosomal heterogeneity in two pairs of Nile tilapia. (a) Schematic illustration of chromosome heterogeneity detected by two-color CGH analysis. (b) XX metaphase from a female tilapia. (c) XY metaphase from a male tilapia. Signals for XX-derived probe (green) and YY-derived probe (red) are seen on the largest pair of chr 1 (arrows) and a pair of small chromosomes (asterisks).
