From a pure safety standpoint, It depends how similar the phenotypes of the parents are. Genetically healthy cousins are probably no big deal. Genetically healthy half sisters/brothers are probably, again, safe. Genes don't know about &quot;families&quot;. The problems associated with incest arise because of similarity between the genes leading to damaging recessive traits being expressed more frequently in homozygous parings.
