The diploid sets of chromosomes comprise 18 pairs of two-armed chromosomes (FN=72) in each species. A triploid form was discovered in A. rosea (3n=54, FN=108). Considerable variation of chromosome number were noted within the same preparation. %N 1 %K Olygochaeta, Lumbricidae, Aporrectodea, karyotypes, chromosome numbers. %P 59-62 %V 1 %D 2007 %I International Journal of Plant and Animal Cytogenetics, Karyosystematics, and Molecular Systematics %L zu28971
