Abstract
|
|
|
|
Cytogenetic features of three ascidian species were studied with specimens obtained from Korean coastal areas. The gonadal tissue was processed in order to obtain mitotic and meiotic chromosomes. The chromosome numbers of Amaroucium pliciferum turned out to be 2n=26 and n=13 with 2sm, 3st, 8t and Halocynthia roretzi to be 2n=16 and n=8 with 6m, 2t. Dipioid number of chromosomes in Dendrodoa aggregata was 64 with 32t. The karyotypes of these Korean ascidians were reported for the first time.
