한국산 뾰족쨈물우렁이 ( Oxyloma hirasei ) 의 염색체 연구

Chromosome Study on the Oxyloma hirasei ( Gastropoda : Succineidae ) in Korea

Abstract

The mitotic and meiotic chromosomes of Succineidae snail one species, Oxyloma hirasei(Pilsbry), were investigated by mians of air-drying mithod. The diploid chromosome numbers were n=18, 2n=36. Chromosome complements of this species consist of seven pairs of metacentrics and 11 pairs of submetacentric chromosomes. Spermatogonial metaphase chromosomes range in length from 4.80${\mu}{\textrm}{m}$ for the largest pair to 1.44${\mu}{\textrm}{m}$ for the smallest pair.
