Answer:

A) 0%

Step-by-step explanation:

a cross between dominant red flowers (RR) and white flowers recessive (rr)

so pink will be heterozygous condition (Rr)..

due to incomplete dominance:

so cross between pink flowers (Rr) are crossed with white flowers (rr)

r r

R Rr Rr

r rr rr

So Rr (heterozygous Pink flower) ------- 50 %

rr (recessive white flower )------------------50 %

so 0 % will be red flower.
