You have isolated a set of five yeast mutants that form dark red colonies instead of the usual white colonies of wild-type yeast. You cross each of the mutants to a wild-type haploid strain and obtain the results shown below;
What do these results tell you about each of the mutants?

#Unit 8. Inheritance Biology
  1. All the mutants 1, 2, 3, 4 and 5 are recessive to wild-type .
  2. Mutants 1, 2, 3 and 5 are recessive to wild-type and mutant 4 is dominant to wild-type.
  3. Mutant 4 is recessive to the wild type while the mutant 1, 2, 3 and 5  are recessive to wild-type.
  4. Mutants 1, 2, 3 and 5 are dominant to wild-type and mutant 4 is recessive to wild-type
