Question

a scientist crosses a plant with red flowers and a plant with white flowers. The off spring will most likely have

a) red flowers

b) white flowers

c) pink flowers

d) red flowers with white patches

Answer 1

really bad question.
if the plants are pure bred, that is homogenous, the offspring are likely to all be red (assuming red is dominant Rw)
If the red plant is not purebred, and carry the allele Rw, then crossing a Rw x ww gives rw, ww, ww, rw or half will be red, half white.

the question should have been
a scientiest crosses a pure bred plant with red flowers with a white flowered plant, the offspring will most likely have..
