Induction of chromosomal and nonchromosomal mutations in Chlamydomonas reinhardi with N-methyl-N'-nitro-N-nitrosoguanidine.
Nonchromosomal mutations in Chlamydomonas reinhardi exhibit uniparental inheritance, with stable properties and irregular segregation patterns, suggesting they may be comparable to chromosomal gene mutations but do not obey classical Mendelian laws.
