You identified a biochemical pathway that produces pigment in a flower. The pathway involves
converting a precursor compound into the pignment. Two genes work one after the other to
carry out the reactions using the precursors produced by the other gene. When you perform a
dihybrid cross, what is the phenotypic ratio (purple:white. you expect to see?
A. 9:7
B. 15:1
C. 9:3:3:1
D. 12:3:1
E. 9:6:1
