In the UK twins who were separated at birth and adopted by different sets of parents later married each other without realizing they were brother and sister. They had their marriage unnulled after finding out the situation.Â
If they had wanted to have kids that would obviously have presented a problem due to the high risk of a defect, but otherwise, at that point does it really matter as it was an innocent situation? Or maybe they just decided it was too weird when looking at each other.Â
For those advocating gay marriage, is there still any basis for familial limitations since the individuals cannot produce children with each other? Or what about a brother and sister marrying, but using the egg or sperm or a third person to avoid genetic defects in children?
