Yes but the most apparent thing when it comes to intelligence comes from how the child is raised and how it recieves it's education, not from the genes.

The Genes play a part, of course, genes play a part in everything. They change constantly to fit what new information is fed to them, but the genes that monitor intelligence only transfer in so small amounts that it does not really affect the child.
