#WILL ZEBRA WORK WITH ZEBRA 2 CODE#
However, although the code is frequently right, it’s often wrong. I report back, bringing samples for a show-and-tell session. Then, a few 11-week generations down the line, bar-coded fish. Over the next few months, I create fish with smudges and blotches, fish with swirls, chess-board fish, fractal fish, kaleidoscopic fish. I throw CRISPR at them, zinc fingers and more. Like their hoofed namesakes, zebrafish have stripe-defining genes it’s just a matter of figuring out where they are. Zebras are unpredictable, rare in California, and they bite.

They slide across another piece of paper. Well, it might work, I tell them, but it’d take decades of research. There’s a big number on it, preceded by a dollar sign. They slide a piece of paper across the table. I shake my head it’s impossible, irresponsible and probably illegal. Think how much money our supermarkets will save. Self-bar-coded chick peas, bananas, halibut. From one such experiment, anything is possible. Not one, but modify enough stripy genes, and you could create a zebra that scanners will recognize. Before they can attempt an answer, I continue: Anyway, it won’t happen. Tweak those genes, et voilà: a zebra dressed in its own personal bar code.Īnd why would I want that? I ask.


Zebra genes contain the recipe for those stripes, right? I’m a CRISPR guy, so the role of genes is hardly news to me. You’ll re-engineer plants and animals so they grow their own bar code. Picture a lettuce leaf, they say, with a bar code drawn in chlorophyll, or a lemon with a scarlet bar code embedded in its peel. They call me a smart ass.Ī zebra’s stripes are meaningless, I tell them. You can’t tell, I say zebras don’t fit on the supermarket scanner. What information is in its bar-coded stripes?
