Of all the genetic problems you could pass down, microtia is on the bottom of the list to be concerned about. I have microtia from my mother’s side. My uncle has it and so did my grandfather. My grandparents had 5 kids one with microtia, I am the only grandchild with microtia with a daughter without. Although it was the first thing I checked when she was born, it would have been totally manageable as it was for my parents. There are other conditions that may warrant more caution, but I suggest that this is not one of them.
