I absolutely love this subject. First of all, I have a degree in Molecular Biology, and any time I get to talk about the subject of Genetics I reach the equivalent of nerd Nirvana. Second, it brings back memories of my childhood in Europe, where my grandma, of all people, did genetic experiments on her garden flowers.
My grandmother wasn’t a Scientist, Molecular Biologist, or any other type of Evil-James-Bond-Character. She was an incredibly sweet old lady who lived all of her life in Europe, and meticulously nurtured her gardens, rich with fresh seasonal fruit, vegetables, and flowers. One thing that she impressed into my memory was when she successfully crossbred a River Birch tree with red roses. Just imagine a garden of wild roses, philodendrons, vividly colored lilies, and in the middle of all of that, a twenty foot tree just covered with blooming red roses. Awesome!
