I hope you don't mind, but I have a curiosity question on my part. Were the
families with multiple fathers or mothers a mistake, just duplicates (same
Family.ID & Sample.ID), or more like an "intermixed" family due to divorce
and remarriage. Or even, like in some countries, a case of polygamy? Sorry,
I just get curious about the strangest things sometimes.
