Flow cytometry was used to examine the patterns of somatic polyploidy and to determine the haploid genome sizes in Daphnia. The average proportions of polyploid nuclei among adult animals of D.pulex, D.longispina, D.pulex × D.longispina and D.magna equalled 27, 24, 24 and 24%, respectively. Both int...
