Inbreeding causes genetic diseases.
I think Angels father was a heavy chain smoker and stopped smoking when he got throat cancer.
Sometimes, mutagens like radiation, UV light and cigarettes can cause mutations, but not all mutations have an outside cause. It may be due to spontaneous breaking of chemical bonds in the DNA or errors in the way in which DNA is copied.
As polydactyly is usually caused by a random mutation, only one of the parents would be affected and so inbreeding does not increase the likelihood of a child developing polydactyly.
If both parents were polydactyls, then the likelihood of the child being affected is 75% but this is not increased by inbreeding.
