My guess is that Yoda's species may have some sort of asexual reproduction capability. That way if there is only one, they can still produce offspring. Maybe by laying some sort of egg that gestates for 100 years before hatching.
In the end that offspring would essentially be a clone as no mixing of DNA is involved.
So if Yoda laid an egg 145 years before he died and hid it with someone, this could indeed be Yoda's baby and clone at the same time.
