The children of incest on the first level (Mother/son= child etc) there will be no physical traits that are not in any other child born to parents not related at all. The rate of birth defects of completely UN-related couples is about 1.5% to 2.5% those born from incest are about 2% to 3% chances of birth defects of any kind. This is true for the first child. If the incest is repeated with the Grandparent/ child (second level) it goes to 5% to 6%. Then great grandparent/child the rate jumps to 10% or higher. This is true if brother/sister or father/daughter.
Should the incest child have children with someone not related the chances fall back into the normal range of unrelated couples.
There are also some good things associated with incest. If there is a problem in the DNA gene pool some of them can be removed and do not show up in children of incest children.
I hope this brief explanation helps. If you want to know more google incest and look for helpful information.
