Chromosomes with FISH signal are indicated (+). YAC 857_b_10 (15) was used as reference. Most probes were found to hybridize to the same set of chromosomes, but clones 662K13 and 670G10 also detected chromosomes 2, 10, 12 and 17 but not 11 and Y, and PACs 668N10 and 670G14 hybridized to chromosomes 2, 10 and 17, but not 11 and Y. There is an 57% overlap in chromosomal localization for all probes used, since chromosomes 1, 3, 9, 13, 14, 15, 21 and 22 make up the chromosome set labeled by all probes.
