Experientia Aims and scope Submit manuscript

Riassunto

I tre Sirenidi viventi hanno 46, 52 e 64 cromosomi; il corredo diS. lacertina sembra tetraploide (4n=52). Viene fatta l'ipotesi che anche i corredi delle altre due specie derivino per (allo-)poliploidia da corredi a minor numero cromosomico, come si ritrovano nelle famiglie “superiori” dell'Ordine.
