Patty & Cathy, Move Over

Okay, this really has nothing to do with insurance, but as the uncle of twins (both Eagle Scouts, BTW), I found this quite fascinating:

"Researchers discovered twins who are identical on their mom's side of the equation but share only half their genes from dad."

It appears that one egg was fertilized by two sperm cells, resulting in twins that are neither identical nor fraternal.

Or maybe both?

Interestingly, there don't seem to be any IVF issues at play here; they were apparently conceived "the old-fashioned way." There are some health issues: one has abnormal genitalia. On the other hand, they seem to be developing normally.

Hopefully, they'll continue to do so.
