There's another place to store information which isn't in the genes themselves but in the mapping of codons to amino acids. This location would be invariant across generations.
This paper on "biological SETI" made some noise when it came out and then disappeared, literally gone from arxiv, perhaps because the crackpot smell is too strong? I am curious if it merited either debunking or further study but didn't see much of either. If there is a signal there, it seems more plausible that prior inhabitants put it there than ET.
