it has a much greater possibility for genetic impairment implications either immediately thru the child born or later down the gene line. and fuck ur apostrophes and ignorance.

I'm not an atheist. The secular answer is that it has a high chance of inbreeding causing health problems for the child. On top of that, humans are generally programed to avoid incest. Any animal is through evolution. Just because the actors who happened to be unlikely exceptions are OK with incest doesn't mean that the child is, and the family dynamics growing up will harm him/her a lot psychologically.

Swimming in your own gene pool is extremely dangerous. The risk of numerous hereditary diseases surfacing is big. Physical defects are more likely to show. All in all, any logical biological being would do well to avoid incest.

similar mutation are there in the same gene pool,which cause hereditary diseases and genetic defects
