I also was under the impression that inbreeding within the same generation (i.e. brothers and sisters) was not as bad as back-crossing (child with a parent). These back-crosses are more likely to produce the mutant phenotypes.
On average, a pair of siblings are as closely related as a parent-child pair, but siblings vary randomly in how closely they're actually related.
