Hi,
I was actually reading something about this a couple of days ago that mentioned several ways different genetics can exist in the same individual.
I may have misunderstood because it said every female human was a mosaic because only one of the x chromosomes is active in each cell and one of the xx pair comes from the father?
Also something about marmosets commonly having their brothers sperm!
Apparently chimerism isn't always a rare occurance and can sometimes even be more common than what we think of as "the norm" depending on the species etc.
