title: ZOO-FISH suggests a complete homology between human and capuchin monkey (Platyrrhini) euchromatin.
abstract: Chromosome comparisons using in situ hybridization of all human chromosome-specific libraries on Capuchin monkey (Cebus capucinus, Cebidae, Platyrrhini) metaphases were performed with a new technique simultaneously revealing a G-banding and chromosome "painting." A complete homology between human (HSA) and C. capucinus (CCA) chromosomes was demonstrated, except for constitutive heterochromatin. Eleven C. capucinus chromosomes are homologous to 11 human chromosomes: CCA 2 = HSA 4; CCA 3 = HSA 6; CCA 12 = HSA 9; CCA 16 = HSA 11; CCA 10 = HSA 12; CCA 11 = HSA 13; CCA 20 = HSA 17; CCA 8 = HSA 19; CCA 23 = HSA 20; CCA 24 = HSA 22; and CCA X = HSA X. Ten C. capucinus chromosomes are homologous to parts of human chromosomes: CCA 13 = HSA 8q; CCA 14 = HSA 2q; CCA 15 = HSA 1p + 1q proximal; CCA 17 = HSA 7 part; CCA 18 and 19 = HSA 3 part; CCA 21 and 22 = HSA 1q distal; CCA 25 = HSA 10p; and CCA 26 = HSA 15q part. Six C. capucinus chromosomes are homologous to parts of two human chromosomes: CCA 1 = HSA 5 + 7 part; CCA 4 = HSA 2p + q proximal + 16q; CCA 5 = HSA 10q + 16p; CCA 6 = HSA 14 + 15 part; CCA 7 = HSA 8p + 18; and CCA 9 = HSA 3 part + 21. Many previous banding comparisons were confirmed but several cryptic or complex rearrangements could be identified. With the C. capucinus karyotype having been shown to be fairly ancestral, this comparison opens the possibility to compare human chromosomes to most Cebidae species.
