First, some background info: I was born with pre-axial polydactyly. Not a severe case, but basically I had a growth hanging off of my left thumb when I was born. It was removed very soon after, and so I've had a charismatically crooked thumb throughout my 20 years of existence, which is going to be "fixed" surgically in about a month. It has never given me much trouble. At least none worth mentioning.
From what I've gathered, I am the only person in my family to ever have been born with an extra digit, at least as far as I know, so it is not a family trait that's been passed down to me. My two siblings do not have it. Neither do my parents, or my grandparents. Just lucky ol' me. So it seems to have been a random occurrence. It was not accompanied with any other physical conditions or deformities. It's just a jacked up thumb. Now I understand that polydactyly by itself is a dominant trait when genetic, but I've also heard that it is not always genetic, and in fact there is no explanation for it most of the time.
Okay, so onto the question: given the previous information on my polydactyly, what do you educated folks think are the chances that I will pass it onto my children? I don't know if I'd be willing to pass on this trait to a child or multiple children if it is in fact a genetic mutation that I possess. And, quite frankly, it is pretty disheartening to know that I may possibly be the carrier of a "bad gene," because I really wanted to have a lot of kids and it kind of feels shitty to be a defective human.
