Two plants, each with CcPp are crossed:

CcPp x CcPp

Offpring

1 CCPP - purple

2 CCPp - purple

2 CcPP - purple

4 CcPp - purple

2 Ccpp - white

1 CCpp - white

1 ccPP - white

2 ccPp - white

1 ccpp - white

Proportion of offspring with white flowers = 7/16

Proportion of offspring with purple flower = 9/16
