You need to respond to each of the possible choices in the question below.

Imagine that the doughnut is a sexually reproducing animal and that a single enzyme forms the hole. All doughnuts observed in the past have had holes. Suppose a mutation occurs in one gene of the doughnut such that it now codes for an inactive protein instead of the hole-forming enzyme. Which of the following predictions would be most likely in descendants of this mutant doughnut?

a. All members of the next genration will have holes.

b. Heterozygous doughnuts will not have holes.

c. If the cell in which the mutatin occurs undergoes mitosis, subsequent generations of doughnuts will all have holes.

d. The next generation will all be holeless.

e. Past generations of doughnuts have all had holes.
