摘要

Abstract

We performed a karyotype analysis on four species from Phylum Nemertea using regenerating somatic cells. Two palaeonemertean species

Cephalothrix hongkongiensis and Cephalothrix sp.

had the same chromosome number (2n=28)

but different karyotypes (16 m+10 sm+2 st

NF=54 and 22 m+4 sm+2 st

NF=54

respectively). The karyotypes of the two heteronemerteans

Notospermus geniculatus and Ramphogordius sanguineus were 2n=38

30 m+6 sm+2 sm/st (NF=76/74) and 2n=56

48 m+4 sm+4 sm/st (NF=112/108)

respectively.
