Incest between Siblings is far more likely to make the child be born with many genetic defects. Parent-Child incest does the same too.

Between cousins, it's less likely. The further away the cousin, the less likely it is. I think starting from your 2nd or 3rd cousin, the incest is somewhat minimal in effect.
