Is this what Kate and William's kids will look like when hey are all grown up?
Well, according to the genealogy experts at, uh, myvouchercodes.co.uk who commissioned the pictures, it is.
We're not so sure, but if there's some cut-price groceries out there, we're keen.
Jenny Chen, a graduate student from the Broad Institute of Harvard-MIT, which is dedicated to genetics/genomics research say that the child has a 50% chance of having green eyes (like Kate) and 50% chance of having blue eyes (like Will).
