title: Evidence for the differentiation of wild-type alleles in different species of neurospora.
abstract: Wild-type alleles at the peak locus of Neurospora have been transferred by backcrossing from N. sitophila and N. tetrasperma to N. crassa. In the genomic background of N. crassa the different wild-type alleles show strikingly different dominance relations with Pk-4, a dominant peak mutation in N. crassa.
