Maybe a button in the settings where you can choose to enable or disable genetics would be a great option (not sure how possible that would be though, lol). That way if you wanted the babies to match the mom and dad you would have the option. Or, like me, if you prefer it to really be a surprise you could turn it off and have a family that looks nothing like each other. Lol!

I personally don't want my children to become 'genetically correct' unless I at least have the option to make them random. Either way though the game is a blast and the people are so cute in VF2.
