Blind mole-rats of the genus Nannospalax have wide chromosome variability. Ten chromosomal forms in lesser mole-rats N. leucodon (Nordmann, 1840) have been described in Bulgaria between 1978 and 1983. No karyological studies have been carried out since then. In this study, we present new karyotype from Ravno Pole Village near Sofia. Karyotyping was carried out based on immunocytochemical analysis of spread synaptonemal complexes (SC). An SCs study of N. leucodon has been conducted for the first time. It was found that the animals had 2n=56, NFa=84 and NF=88. Fifteen biarmed chromosomes [2 metacentrics (M), 3 submetacentrics (Sm) and 10 subtelocentrics (St)] and 12 acrocentrics (A) were identified in the SC's karyotype. The X chromosome is a medium Sm. The Y chromosome is a small St. A similar mole-rat's karyotype was previously described in other study from Novo Selo near Plovdiv, however with a different chromosome combination. We suppose that these two populations with same 2n, NFa and NF but different chromosome morphology are most likely independently separated chromosomal forms. [ABSTRACT FROM AUTHOR] |
