| Do you know if it is identical or fraternal? An identical twin is caused by the embryo splitting and is mostly random. It may be heritable to a very small degree but nothing to certainly bank on.
A fraternal twin is caused by hyperovulation and may be heritable to certain extent.
In the interest of disclosure I may be more sympathetic than most as I’m an identical twin. My wife has fraternal twins in her family but both our kids are singles.
A friend of mine is a fraternal twin and she had a set of fraternal twins as well.
I have some cows that have multiple twin births in their life. I’ve not kept track whether their daughters have higher percentage of twins also but anecdotally can’t say I’ve noticed a real trend.
