Control of Recombination within the Nitrate-2 Locus of Neurospora Crassa: An Unlinked Dominant Gene which Reduces Prototroph Yields

Abstract

The frequency of formation of prototrophic recombinants in crosses between all tested pairs of eight alleles of the nitrate· 2 locus in N. CTassa is subject to a reduction of about eightfold by a dominant gene rec-z+. rec-z is unlinked to nit-2 and is not identical with rec-3 or rec-x.
