Why is it not allowed that sibling or relatives not get married to eachother
is it illegal?
It's illegal because if two genetically similar people (like siblings or cousins) get married, their children are much more likely to have problems like mental retardation and birth defects.
I mean just the thought seems weird to me, and if relatives too close had children they would probably have some kind of disability.
How you worded your question.... Actually it's prefered that you don't marry relatives... To answer what I think you meant... We wouldn't want too much inbreeding to go on...
because if you do marry and have babies with relatives chances are that they are going to come out with health issues and deformed
Because that's gross man. Come on.
Incest is illegal, unhealthy, and unnatural. It's also rather disgusting.
You can't marry a relative because it's illegal. Also, if they have kids, the kids could have mental disabilities, mental retardation, and much more. Also, come on, use your common sense! You would be an outcast!
It is illegal because then your kids will act "high" if u know what I mean.
