Abstract excerpt
As the level of ploidy rises in Pullularia pullulans, this causes an increase in the frequency of spontaneous and UV-induced auxotrophic mutants as well as mutants with a modified respiration activity while the frequency of morphological mutants decreases. The latter can arise as a result of recessive and dominant mutations. A higher frequency of morphological mutants in the haploid may be result of recessive...
