JOURNAL FREE ACCESSIn Amami black rats the location of ribosomal 18S+28S rRNA genes is found to be in the centromere region of nos. 8 and 13 chromosomes by the in situ hybridization technique by the use of radioactive complementary rRNA. In the chromosome 3, small silver cluster was rarely observed. This means that the copy numbers of rRNA genes would be extremely fewer in pair no. 3 than those of pair nos. 8 and 13.View full abstractDownload PDF (429K) -

JOURNAL FREE ACCESSSomatic chromosomes of two representative species of the genus Hynobius are observed. The diploid number of H. naevius and H. nebulosus are confirmed to have 56. Twenty-eight pairs of homologues are classified into four groups to facilitate the comparison of each karyotype. The chromosome morphology constituting both karyotypes is similar in general, but not identical with each other. An unambiguous difference occurs in the medium-sized chromosomes (nos. 10-13). Consequently, it results the different fundamental number (FN) to two species, 90 for H. nebulosus and 92 for H. naevius. The karyotype of H. nebulosus, which is the most common species and is widely distributed in the western Japan, is not exactly the same with that of a previous work. The minor difference found in the small-sized chromosome groups (nos. 14-18 and 19-28) suggests the microchromosomal variation according to the difference of the locality.View full abstractDownload PDF (550K) -
