Question

When a red flowered homozygous snapdragon plant is crossed with a white flower plant, what colour is produced in F${}_1$?

• A. Red
• B. White
• C. Pink
• D. All of the above

Answer 1

The correct option is C Pink

Red coloured homozygous plant: RR
White plant: rr
Crossing between both: RR x rr
F${}_1$ generation: Rr (Pink coloured flower). This is an example of incomplete dominance.

Thus, the correct answer is option C.
