It's obviously imprinting, but the mechanism for that imprinting is implemented in your neurons, which are defined by your genes. Ultimately, it's a "feature" that wouldn't be there if it wasn't for something in your genes encoding for it! The question is how is that encoded, not just in your genes, but in the final neurons? There are hundreds of trillions of synapses in the brain that a few megabytes of genes somehow shaped into: "be attracted to faces almost, but not exactly like your parents"... but not actually repulsed, because you have to get along nicely with your parents and not just run away in terror.
