Nucleolar organizer regions in Mesocricetus brandti (Nehring, 1898) (Mammalia: Rodentia) from the Yozgat and Tokat provinces of Turkey


Abstract: Mesocricetus brandti possesses a diploid chromosome number of 2n = 42, a fundamental number of NF = 82, and a fundamental number of autosomal arms of NFa = 78. The chromosome set consists of 17 meta-submetacentric pairs, 2 subtelocentric pairs, and 1 acrocentric pair. The X chromosome is large and metacentric while the Y is medium-sized and metacentric. The nucleolar organizer regions were located at the telomeric region of 7 biarmed autosomes and at the centromeric region of 1 acrocentric autosome.
