In a Flowering Plant, a Mutation in a Gene Controlling

Multiple Choice

In a flowering plant, a mutation in a gene controlling flower structure results in flowers with extra petals. A mutation in another gene results in no flowers (flowerless) . Both mutant phenotypes are recessive, and the two genes assort independently. If a plant heterozygous for both mutations self-fertilises, which of the following ratios would you expect in the offspring?

A) 9 wild type: 3 extra petals: 3 flowerless: 1 extra petals, flowerless
B) 9 wild type: 3 extra petals: 4 flowerless
C) 9 wild type: 3 flowerless: 4 extra petals
D) 1 wild type: 1 flowerless: 1 extra petals: 1 extra petals, flowerless
E) 1 wild type: 2 extra petals: 1flowerless
