The Karyotype of Chukotka Chars from the Estikhed Lake (Eastern Chukotka)

The Karyotype of Chukotka Chars from the Estikhed Lake (Eastern Chukotka) The karyotype of chars from the Estikhed Lake (Eastern Chukotka) was examined. This karyotype comprises 78 chromosomes, NF = 98. Marker chromosomes include one pair of submetacentrics, one pair of large acrocentrics, and one pair of large subtelocentrics with very short second arms. Nucleolus organizer regions are located in telomeric regions of short arms of marker submetacentric chromosomes. Small heterochromatin blocks are observed in centromeric regions of most chromosomes. The Chukotka char karyotype is very similar to that of Taranetz charSalvelinus taranetzi from the Achchen Lake: these karyotypes differ only in stability of the chromosome number. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals

Abstract

The karyotype of chars from the Estikhed Lake (Eastern Chukotka) was examined. This karyotype comprises 78 chromosomes, NF = 98. Marker chromosomes include one pair of submetacentrics, one pair of large acrocentrics, and one pair of large subtelocentrics with very short second arms. Nucleolus organizer regions are located in telomeric regions of short arms of marker submetacentric chromosomes. Small heterochromatin blocks are observed in centromeric regions of most chromosomes. The Chukotka char karyotype is very similar to that of Taranetz charSalvelinus taranetzi from the Achchen Lake: these karyotypes differ only in stability of the chromosome number.
