C-banded karyotype and nucleolar organizer regions (NORs) of wild boar, sus scrofa (Artiodactyla: Suidae) from Anatolia

The present study reports the karyotype, C-banding, and nucleolar organizer regions (NORs) of 6 Sus scrofa (Linnaeus, 1758) males from Anatolia. The karyotype of S. scrofa comprised (2n) 38 chromosomes, the number of chromosomal arms (FN) was 64, and the number of autosomal arms (FNa) was 60. C-positive regions appeared to be restricted to the centromeric regions of autosomes 1, and 13-18, and the entire long arm of the Y chromosome. | Turk J Biol 33 (2009) 29-33 © TÜBİTAK doi: C-Banded Karyotype and Nucleolar Organizer Regions (NORs) of Wild Boar, Sus scrofa (Artiodactyla: Suidae) from Anatolia Atilla ARSLAN1, İrfan ALBAYRAK2 1 2 Department of Biology, Faculty of Science and Arts, Selçuk University, 42031 Konya - TURKEY Department of Biology, Faculty of Science and Arts, Kırıkkale University, 71450 Kırıkkale - TURKEY Received: Abstract: The present study reports the karyotype, C-banding, and nucleolar organizer regions (NORs) of 6 Sus scrofa (Linnaeus, 1758) males from Anatolia. The karyotype of S. scrofa comprised (2n) 38 chromosomes, the number of chromosomal arms (FN) was 64, and the number of autosomal arms (FNa) was 60. C-positive regions appeared to be restricted to the centromeric regions of autosomes 1, and 13-18, and the entire long arm of the Y chromosome. Some autosomes had very slight C-bands. The X chromosome appeared to be entirely euchromatic. NORs were identified by the silver-staining technique and were observed on secondary constriction sites of 2 metacentric chromosomes pairs.

S. scrofa’nın karyotipinin (2n) 38 kromozomdan oluştuğu, temel kromozom kol sayısı (FN) 64 ve otozomal kromozom kol sayısı (FNa) 60 olduğu gözlendi. C-pozitif bölgeler, 1, 13-18 nolu kromozomların sentromerik bölgelerinde ve Y kromozomun uzun kolunun tamamında göründü. Bazı otozomlar çok hafif C-bantlara sahiptir. X kromozomun tamanının ökromatik tipte olduğu belirlendi. Gümüş boyama tekniği ile tanımlanan nükleolar organizatör bölgeleri (NORs), iki çift metasentrik kromozomdaki ikincil boğum yerlerinde bulundu. Anahtar .
