Abstract

The karyotype of the brightbelly sculpin Microcottus sellaris (Gilbert, 1896) (family Cottidae) from the Sea of Japan and Sea of Okhotsk has been studied for the first time. The karyotype is stable; it includes 42 chromosomes (2 metacentric, 2 submetacentric, 32 subtelocentric, and 6 acrocentric chromosomes); the number of chromosome arms is 46. A comparative analysis of the basic karyotype traits was carried out for M. sellaris and for the Far Eastern species of the genus Myoxocephalus (M. stelleri from the Sea of Japan and Sea of Okhotsk, M. brandtii, M. jaok, M. ochotensis, and M.polyacanthocephalus). The traits that allow differentiation of M. sellaris from species of the genus Myoxocephalus, as well as the common traits indicating their relationship, are identified.

Brightbelly Sculpin Microcottus sellaris的核型(吉尔伯特,1896年)(科:Myoxocephalinae)

摘要

首次研究了来自日本海和鄂霍次克海的亮腹杜鹃Microcottus sellaris(吉尔伯特家族,科蒂科)的核型。核型稳定;它包括42条染色体(2个亚中心,2个亚中心,32个亚中心和6个顶中心染色体);染色体臂数为46。对蝶sell和远东物种Myoxocephalus(日本海的斯特雷勒氏菌和鄂霍次克海的勃氏成虫)进行了基本核型性状的比较分析M. jaokM. ochotensisM. polyacanthocephalus)。确定了可以使M. SellarisMyoxocephalus属的物种区分开的特征,以及表明它们之间关系的共同特征。
