4. A pure breeding variety of ochro plant having leaves that were irregularly shaped
(pinnate) was crossed to a variety that had normal leaves. All the F₁ had normal leaves.
Two of the Fi were interbred to produce F2. Of the F2, 145 had normal leaves and 9 had
pinnate leaves. These crosses are shown below:-
P generation
