Calling geneticists. How can this be?
I'm sorry for asking a simple question, but I just don't understand. There is a discussion going on elsewhere about selfing the yellow-flowered Episcia 'Suomi'. But it seems that all the offspring (at least the ones the people on the forum have grown out) always give red or orange flowers. Red/orange flowers are the most common for the genus Episcia. So my question is, how can it be that a yellow-flowered Episcia crossed with itself not produce any plants with yellow flowers?
Thanks so much.
