Question

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%

Answer 1

A, 0%, 50% will be pink and the other 50% will be white

Answer 2

0%

A cross between Rr plants and rr plants will yield a ratio of 2Rr:2rr. If Rr represents pink flowers, then none will be red.
