Genetics Question
Parents
ppRR (rose comb) PPrr (pea comb)
Offspring
PpRr (walnut comb)
permitted to interbreed amongst one another
Yields 9:3:3:1 ratio (Walnut😛ea:rose:single)
Can anyone help me in identifying the pathway that permits the 2 enzymes that arise from genes P and R (when functional) that produce a walnut comb.
e.g. Single comb ----- Enzyme A (P functional)---> rose comb ------------Enzyme B (R functional)----> walnut comb
This given pathway of course doesn't yield the correct results because should p be non-functional, yet R be functional, then the rose comb phenotype still arises. Also, the same is true should the two genes be reversed (e.g. functional P and nonfunctional R). P and R need to be functional in order for walnut comb to arise.
Any ideas fellas?
