Gretchen Ponce · Answer 1

The correct answer is: A. All will have both red and white flowers.

If camellia plant with red flowers (RR) is crossed with a camellia plant with white flowers (WW), then

P: RR x WW

F1 generation: RW RW RW RW

This means that all of the offspring will have both colors. Codominant means that red and white are equally dominant (both expressed).
