Syntenic homology of human unique DNA sequences within chromossome regions 5q31, 10q22, 13q32-33 and 19q13.1 in the great apes

Homologies between chromosome banding patterns and DNA sequences in the great apes and humans suggest an apparent common origin for these two lineages. The availability of DNA probes for specific regions of human chromosomes (5q31, 10q22, 13q32-33 and 19q13.1) led us to cross-hybridize these to chim...
