The "gene-culture coevolution" terminology sucks

A big improvement would be "gene-meme coevolution". Or if you really want to have the word "culture" in there, "organo-cultural coevolution" would at least be logical.

However, "gene-culture coevolution" is ugly and wrong. I wince with a kind of sympathetic embarassment for the speaker, whenever i hear the term mentioned.

This terminology is a product of using informational conceptions of culture. It is what you are forced into doing if you don't have the "meme" concept down.
