... The general meiotic mutant him-6 was explicitly tested for the production of nullisomic and disomic gametes for each chromosome in turn (Haack and Hodgkin, 1991). The results showed that all of these possible abnormal gamete types were being generated, at roughly equal frequencies. These experiments ...
