The chromosome numbers of five species in two families of Korea are investigated: Odontobutis platycephala, O. interrupta, and O. obscura in Odontobutidae, and Cottus koreanus and C. hangiongensis in Cottidae. In Odontobutis species, the three species showed the diploid chromosome number, 2n=44 (NF=...
The chromosome numbers of five species in two families of Korea are investigated: Odontobutis platycephala, O. interrupta, and O. obscura in Odontobutidae, and Cottus koreanus and C. hangiongensis in Cottidae. In Odontobutis species, the three species showed the diploid chromosome number, 2n=44 (NF=44) telocentric chromosomes. In Cottus species, the mitotic chromosomes from 24 groups with two chromosomes each indicated that it is a diploid. The karyotype of C. koreanus and C. hangiongensis is 2n=48 and NF=52. These species is the first report on the chromosomes and the karyotype analysis except O. platycephala. Our findings provide cytotaxonomic evidence for the species distinctness of these five species whose descriptions were based primarily on external morphology.
