A strange thing happened to one of our roses, last year these roses were red, this year they are yellow. I wonder how that happened.

Did some research on that and found this:
'There’s two possibilities. The first is that the red rose is due to spontaneous mutation in whatever founder cells gave rise to that particular branch of the tree. That’s always possible, though I believe red is dominant over white, and so white is probably a loss-of-function trait and thus isn’t likely to spontaneously revert to red flowers. A more likely explanation is that your plant was produced via a graft of two different types of rose plants, one red and one white. Grafting is a common technique and may result in a plant that is genetically non-uniform (including, even, different species of plant)'
That seems to be your answer
