From the point of view of genetics the entire question as to if language is genetic seems malformed. Genes code for proteins NOT traits. Genes do not code for hands. Hands are made of many proteins that are encoded by genes. Lactose intolerance is however a traits that boils down to one protein (the enzyme lactase) so one gene can change that trait. Most of the time it isn't like that. With language it isn't going to be like that. There are multiple structures in the brain, vocal chords, nerves, etc. that all play a role in language. All those structures are made of proteins and encoded by genes. Changes in those genes can have some effect on language in various ways. For instance genes like FOXP2 and ASPM probably have some role in language but there isn't one magic language gene. It's more minor things.

People don't talk to dogs in Kenya? How do they train them? Are they not kept as pets there?
