So: There are no unique “tree” genes. It’s just a different expression of genes that plants already use. Analogously, you can make a cake with flour, sugar, eggs, sugar, butter, and vanilla. You can also make frosting with sugar, butter, and vanilla – a subset of the ingredients you already have, but in different ratios and use
Actually, you can even make a frosting with flour, sugar, eggs, sugar (uh… you listed ‘sugar’ twice), butter, and vanilla—i.e., the exact same ingredients!
(The flour and the butter make a roux, the eggs and the sugar make a zabaglione base, then you mix both things together, add vanilla, and bam! Meanwhile, a cake made from the given ingredients would be a chiffon cake.)
EDIT: But I would not recommend using this type of frosting with this type of cake.
