Abstract
A NUMBER of independently induced mutant alleles are known at the ‘amination-deficient’ locus in N. crassa. Previous work with four different am mutants, designated am 29, am 32, am 47 and am R has shown that certain combinations of these am alleles in pairs in heterocaryons were complementary1,2. In addition, apparently true wild-type ascospores were found in low frequency in the progeny of most crosses between strains which carried non-complementary am alleles.
