To study genes that create the purple flower color in peas, you isolate 4 amorphic mutations. Each results in a flower with a different color, described mutant a = blue mutant c = pink mutant b = white mutant d = red A. In tests of double mutants, you observe the following phenotypes: mutants a and b = blue mutants b and c = white mutants c and d = pink Assuming you are looking at a biosynthetic pathway, draw the pathway indicating which step is affected by each mutant. B. What is the expected flower color of a double mutant of a and c?

Question

To study genes that create the purple flower color in peas, you isolate 4 amorphic mutations. Each results in a flower with a different color, described

mutant a = blue

mutant c = pink

mutant b = white

mutant d = red

A. In tests of double mutants, you observe the following phenotypes:

mutants a and b = blue

mutants b and c = white

mutants c and d = pink

Assuming you are looking at a biosynthetic pathway, draw the pathway indicating which step is affected by each mutant.

B. What is the expected flower color of a double mutant of a and c?
