Answer:

A) 0%

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.

Answer:

0%

Explanation:

50% will be pink

50% will be white
