Question

In a cross of heterozygous RW four o'clock plants (RW x RW) what proportion of the seeds will grow to produce pink flowers?

A.) 0
B.) 0.25
C.) 0.5
D.) 0.75

Answer 1

In this question, the parental is heterozygous i.e. RW

Parent: RW x RW

Gametes: R and W

F1: RR ; RW ; RW ; WW

RR is red

WW is white

RW is pink

As you can see, 50% of the F1 generation is having pink flowers. So the answer is 0.5.

Answer 2

The answer is C.) 0.5. Hope this helps.
