My wife is an identical twin and no her sister is not the parent of our daughter.
Didn’t pay attention in high school/college biology brehs
My girl is a twin, this is false.
The children of identical twins are genetically more like half-siblings than first cousins.
And like someone else pointed out, if two sets of identical twins get married and have kids, those children will be genetic siblings.
