Karyotypes of five species and three cultivars of Zantedeschia were studied. Karyotypes were distinct between the evergreen species Z. aethiopica (section I) and all winter-dormant species (section II) studied. The karyotypes were not distinct among species within section II. Z. aethiopica has mostly subtelocentric chromosomes whereas species in section II have only metacentric or submetacentric chromosomes. The karyotype of the summerdormant species, Z. odorata, falls between Z. aethiopica and section II, but is more closely related to Z. aethiopica based on karyotype asymmetry.

Kariotipes van vyf spesies en drie kultivars van Zantedeschia is bestudeer. Die kariotipes van die immergroen spesie, Z. aethiopica (seksie I), het verskil van dié van alle winter-rustende spesies (seksie II) wat ondersoek is. Daar was geen verskille tussen die kariotipes van spesies in seksie II nie. Z. aethiopica het hoofsaaklik subtelosentriese chromosome terwyl spesies in seksie II slegs metasentriese of submetasentriese chromosome het. Die kariotipe van die somer-rustende spesie, Z. odorata, val tussen Z. aethiopica en seksie II, maar is op grond van kariotipe-asimmetrie nader verwant aan Z. aethiopica.
