We hybridized human chromosome paints on metaphases of the pygmy tree shrew (Tupaia minor, Scandentia). The lack of the ancestral mammalian 4/8 association in both Primates and Scandentia was long considered a cytogenetic landmark that phylogenetically linked these mammalian orders. However, our results show that the association 4/8 is present in Tupaia along with not previously reported associations for 1/18 and 7/10. Altogether there are 11 syntenic associations of human chromosome segments… CONTINUE READING
