Researchers Combined Two Yeast Strains of Opposite Mating Type; the a Strain

question 4

Multiple Choice

Researchers combined two yeast strains of opposite mating type; the a strain was resistant to chloramphenicol and the ? strain was sensitive to chloramphenicol. The diploid progeny were allowed to undergo several cell divisions, and then the cells were replica plated on glycerol medium with and without chloramphenicol.
-What results would you expect if mitochondria are inherited biparentally?

• A)Some, but not all, yeast colonies found on the plate without chloramphenicol will also grow on the plate with chloramphenicol.
• B)All of the yeast colonies on the plate without chloramphenicol will also grow on the plate with chloramphenicol.
• C)Many yeast colonies will grow on the plate without chloramphenicol and no colonies will grow on the plate with chloramphenicol.
• D)No colonies will grow on either plate.
