Karyotype of Korean Birds VI. Karyological Anaiysis on Two Species of the Genus Dendrocopos by C-Banding Method

한국산 조류의 핵형 VI. C-Banding방법에 의한 딱다구리의 두 종의 핵형분석

The chromosomal analyses of Dendmcopos major hondoensis and D. leucotos Ieucotos(Picidae:Piciformes) in Korea were performed by conventional Giemsa staining and C-banding method. The diploid number of two species was 2n=90-92 and arm number was AN= 92-96.The conventional karyotypes were very similiar but distribution of constitutive heterochromatin were differ in the first chromosome. The second and several pairs of macro-telocentric chromosbmes have telomeric constitutive heterochromatin.

한국산 Dendmcopos major hondoensis와 D. leucotos Ieucotos의 핵형을 일반염색과 C-banding방법으로 분석하였다. 두 종의 염색체 수는2n=90-92이고, 완의 수는 AN= 92-96으로 동일하게 나타났으며 C-banding 결과 일부 염색체의 장완과 몇 쌍의 단부염색체는 말단에 구조적인 질염색 band가 있었다.
