...child would look like on photoshop? I was curious. I can't find a tutorial for this kind of merge. I want to see one alternative to what a child would look like from one couple. I have googled this but I can never word it correctly. Getting help would be awesome. I would like something for photoshop. I have a lot of experience in this program.

Since genes and biology are a very complex thing, it's even hard for a program to guess what a child would look like. It's no wonder then why you haven't found anything on the internet about this. So it's also no surprise that there isn't any Photoshop tool that can do this either.
