Abstract
한국산 꺽지과 어류 3종에 대한 세포유전학적 기초 자료를 얻기 위하여 염색체 핵형, 적혈구 세포 및 핵의 크기와 DNA 함량을 조사하였다 꺽지 (Coreoperca herzi), 꺽저기 (C. kawamebari) 및 쏘가리 (Siniperca schezeri)의 핵형은 각각 2n=48 (4SM+44A, T), 2n=48 (6SM+42A, T) 2n=48 (4SM+44A, T)이었으며, 암수간 heteromorphic한 성염색체는 발견할 수 없었다. 쏘가리의 적혈구 세포 및 핵의 표면적과 체적은 다른 2종보다 작았다. DNA함량은 적혈구 세포 크기에서 같은 경향을 보여, 쏘가리가 1.47pg/cell로 꺽지 (1.83pg/cell) 및 꺽저기 (1.85pg/cell)보다 유의하게 작았다.

Cytogenetic characteristics of three species in Centropomidae (Coreoperca herzi, C. kawamebari and Siniperca schezeri) were evaluated, based on karyologcial analysis, erythrocytic measurement and genome size estimation using flow cytometry. Modal chromosome number of three species was same as 2n=48. Karyotypes were 4SM+44A ⋅ T (NF=52) for Coreoperca herzi, 6SM+42 A ⋅ T (NF=52) for C. kawamebari and 4SM+44A ⋅ T (NF=52) for Siniperca schezeri. Heteromorphic sex chromosome was not found in both sexes of any species examined, Cellular and nuclear volumes of Siniperca schezeri were smaller than those of other two species, Average amounts of cellular DNA contents estimated by flow cytometry were well coincided with erythrocytic sizes. The estimated genome sizes were 1.83, 1.85 and 1.44 pg/cell for C. herzi, C. kawamebari and S. schezeri, respectively.
