This kind of thing has happened before. female sharks have the ability to hold eggs and sperm until the conditions are right. The longest time I think is around 7yrs.

So if there was no male sperm supplied, do the mother and the baby have the same DNA? Is the baby a clone of the mother?

Yup. That's how they determine it's parthenogenisis vs. long stored sperm

I read about this as well - that's crazy. Quite fascinating scientifically at least!

Probably not much research data on this since it's so rare, but I wonder how the offspring usually fair? I wonder if they are subject to negative mutuations or genetic problems? Are they truly a 'clone'?
