Red flowers (dominant) crossed with white flowers (recessive) can yield pink flowers. pink is the heterozygous condition in a trait that shows incomplete dominance. if pink flowers are crossed with white flowers, assuming random chromosome segregation, what percentage is expected to be red flowers?
a) 0%
b) 25%
c) 50%
d) 100%

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.
