Hoochie [10]

Answer:

7/16

Explanation:

The proportion of the offspring from the cross that will have white flowers is 7/16.

The presence of anthocyanin which determines purple coloration is conditioned by the C_ and P_ alleles. It means that the absence of one or both of C and P will result in white flowers.

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

See the attached image for the Punnet's square analysis of the cross.
