I don't believe it. I would have to conduct this experiment myself and see the actual reaction with my own eyes to believe it. I cannot imagine that knowledge about a smell is passed down to a descendant. Or have an explanation for the mechanism by which this happens. Why does this happen, how is the information transferred? It makes no sense.

Your ability to recognise faces, you surely realise, was passed down to you genetically? It’s encoded as hardware priors in the structure of your brain. So it’s not too hard to extend that to knowledge of a smell, similarly hardcoded somewhere. I’m not defending the original paper btw, which seems to have some faults.

Faces, sure, but a particular face?

If you ever crowdfund an attempt to replicate it, please let me know!
