Red and white roses are cross-bred (neither are dominant). The offspring would be, because of

The offspring would be different depending on what type of breeding you did, because of the fact there are different breeding techniques. Co - dominant means it would be patchy with a combination of both, like when breeding cows. The other technique is incomplete dominance, which is where both the colors (in this case red and white) mix together to make a different color. But to simplify it, it would most likely be half and half because both genes are recessive.
