Seem like I remember something saying it "seems" to skip a generation because if a couple has fraternal twins, but they only have boys, then of course that generation won't have any (since it runs through the female). But the father could carry the gene to pass onto to other females, so if that couples sons had girls, then their daughters could have twins..
Nope, you're right. You inherit the tendency to ovulate more than one egg, which is why is has to be in the mom. You can get it from your mom or your dad, but if your husband's family has the trait, it won't help you. It's not like his sperm will send out little signals to your ovaries to give up more eggs.
I don't think there is any proof to that skipping a generation thing, though. Not sure of that.
It's actually a DEFECT which is why you are more likely to have twins if you are fat, old, or lactating - these things tend to mess with your hormone balance and keep what's normal from happening normally. Generally they make you infertile but I guess on the way to being infertile sometimes you are crazy fertile.
Given that I am over 30, somewhat overweight, and nursing twins... it would probably be just my luck to have twins, when I want one next time. I don't have the family history part, though - I used fertility meds, so who knows. (DH's family has identical twins and some of his family think that's why we have twins - we're not hiding anything, I think people just want to believe what they want to believe)
I wanted twins to make up for the gap between DS and the next child. I needed fertility meds, I wasn't trying for twins per say. I thought 2 together would make up for the gap. I got triplets, but doctors were very pushy about reducing due to "risks" - DH wanted to reduce - I did, and I regret, and I have serious issues because of it. So natural twins would in a way be a hilarious up yours to DH and the doctors... but still ... with all the perks there are to twins... I want a normal pregnancy, babyhood, etc and all for my final, if there is a final. (Well, if there's ANOTHER, I mean)
