My Mom has identical twin sisters, she had identical twin uncles, and my Dad was a fraternal twin. We have some weird genes though. My Mom only had sisters and all of us have only one gender children. All four of us!! 3 of us have only boys, and my one brother has onlyl girls. And now his daughter has all boys and my other brother's son has all boys. My Dad did have 2 sisters though, and 9 brothers!!! Strange!!! :D
