The relative replication times of every band in the standardized 300 band G-band idiogram of the chromosomes of the Japanese macaque are presented, and compared to the human sequence. Many chromosomes thought to be homologous between Macaca fuscata and man on the basis of standard chromosome banding and gene mapping show a conservation of the replication sequence. Other supposed chromosomal homologies between these two species show no good correspondence, and the replication sequence data suggest that these chromosomes have been subject to complex rearrangements. The replication sequence data also point to possible additional chromosomal homologies between man and M. fuscata. Asynchrony in replication time between homologues from the same cell may also be evolutionarily conserved, because these species share a number of asynchronous homologous bands. Replication band sequence data can provide significant information for comparative cytogenetics. However, usually only the full replication R- or G-band pattern has been used for interspecific comparisons. The dynamic sequence data presented here determine the replication time of every band in the karyotype, and provide a quantitatively and qualitatively more sensitive tool to characterize chromosomes. Such data could provide valuable new information on which to make phylogenetic reconstructions, and shed light on the relationship between chromosome change and evolutionary process. Finally, the M. fuscata replication sequence presented here will provide a necessary foundation for future comparisons between apes and man.
