  • In the fresh-water planarians Dugesia benazzii and D. lugubris, diploid amphimictic and polyploid pseudogamic biotypes occur, each of them with a peculiar chromosome cycle. In crosses between diploid biotype (acting as female) and polyploid ones, various degrees may be observed from amphimictic diploid to polyploid pseudogamic offspring. All cytological mechanisms that characterise the cycles of natural biotypes and of hybrids are inherited independently and only rarely can they be found… CONTINUE READING
