Genetically similar couples I believe have a better odds of long term compatability. Before ww2 ive herd there were very happy mariges between brothers and sisters all over Europe? Florida is moving the wrong direction as usual banning cousins marrying. Where high intelliagenc is being attempted in offspring close genetic codes are often the only way to accomplish geniouses to advance our society. Its simply a crewl and inhumain inposition and cival rights violation to say because of a kinship that couples cant cohabitate and marry.
