Genetic would mean that genes get modified.
But there might be other ways that some traits get inherited, eg by changing the cellular environment in the sperm/egg itself which could affect the offspring while keeping the genes the same.

Even the definition of a gene is not very accurate. Many important sequences yield a miRNA or another RNA. Only few sequences yield a mRNA. Some "genes" are just integrated viruses/phages/transposons etc... that were modified. One of the most fascinating one was the retrovirus in regards to the mammalian placenta: https://pmc.ncbi.nlm.nih.gov/articles/PMC4332834/ but there are many more examples. We are all DNA hybrids at the end of the day. The whole species concepts makes very little sense these days, IMO. I can see the use case for eukaryotes, but it makes no sense to me for bacteria yet alone viruses.
