Is sibling incest worse than parent-child incest, or vice-versa?

Consider the following - parent-child incest is considered more morally wrong.
But isn't sibling incest worse from a genetic perspective, since siblings have the exact same genetic data?

Isn't there a bit of contradiction there?

LOL no. Parents and children share exactly half of their DNA. Siblings share *on average* half their DNA. It's random.

Siblings would have the same genetical data, but a parent and child would only share 50% genetical data.
Therefore, a parent and child should be less genetically damaging, yet is regarded as morally worse. Is this not a contradiction

But that's wrong.

Parent A and B have alleles Aa and Bb respectively. They're children will be AB, Ab, aB, or ab with equal probability.

1/4 of siblings will have the same alleles
1/2 of siblings will share only 1 allele
1/4 of siblings will have no alleles in common

So on average siblings will have half of their DNA in common. While each sibling will have exactly half of their DNA in common with a parent.
