| mapping the distribution of the interstitial telomeric (ttaggg)n sequences in eight species of brazilian marsupials (didelphidae) by fish and the correlation with constitutive heterochromatin. do its represent evidence for fusion events in american marsupials? | the c-band pattern and the distribution of the (ttaggg)(n) sequence after fluorescence in situ hybridization (fish), were studied in eight species of didelphidae marsupials: four species with 2n = 14 (marmosops parvidens, marmosops incanus, marmosa murina and metachirus nudicaudatus), two species with 2n = 18 (monodelphis domestica and m. americana), and two with 2n = 22 (didelphis marsupialis and lutreolina crassicaudata). the hybridization signals were observed at both termini telomeres of all ... | 2002 | 12826754 |
