In aerobically cultured yeast, a petite mutant is isolated. To determine the type of mutation causing this phenotype, the petite and wild-type strains are crossed. Such a cross has three potential outcomes.
(a) all wild type
(b) some petite: some wild type
(c) all petite
For each set of results, what conclusion about the type of petite mutation is justified?
¦ HINT: This problem involves the understanding that the petite phenotype is related to mitochondrial function and to how mitochondria are inherited. The key to its solution is to remember that in yeast, inheritance of mitochondria is biparental.
