Osservazioni cariologiche sulla partenogenesi meiotica di Macrobiotus dispar (Tardigrada)
Having found no males during three years of breeding in Macrobiotus dispar the parthenogenesis has been demonstrated. The karyological examination has shown that M. dispar has a diploid meiotic and chiasmatic parthenogenesis and the restitutive process takes place at the beginning of the 2nd oocyte division.
