CC-1148 imp11 (mid) mt-

From Ursula Goodenough, Washington University, May 1981

Phenotype: sex reversal

The imp11 mutant was isolated by Goodenough in the 137c background, and initially characterized as a sex reversal mutant; although isolated in minus, it mated as plus. Subsequently it was found to be a mutation in the MID gene, which is present in the mating-type region only in minus cells and is responsible for minus dominance in mt+/mt- diploids.
