Abstract

top
In a bisexual population of Macrobiotus richtersi from Pisa the chromosomal set is 2n = 12 and n = 6. It is also shown that in the same species, but in a different geographical territory (Modena), is present a parthenogenetic triploid (3n = 18) biotype. This kind of parthenogenesis is ameiotic. In the organs of the triploid individuals the number of cells is similar to that of the diploid population.
