Well, her foals would match one of her sets of DNA.
Actually, no. There have been a couple of case studies of human chimeras. One, the woman's 3 children did NOT match her DNA. The courts were going to take her kids away from her, because their DNA did not match. She was pregnant with her 4th child and the judge (in the court case to remove her kids from her) had someone be there for the birth of her 4th child and was to take a DNA sample right then and there. That baby also did not match its mothers DNA, but it was witnessed that the child did come out of that mother.
They did find that her chlidren matched some of her brothers DNA. And with further testing, they found her DNA that matched her kids in different organs in her body. Not her reproductive organs though.
This was all on the health channel the other night.
I saw that episode and was Wowed by it!!!I did go out and take a look at my stallion's color and looked him over really hard the other night. He seems to have all the same coloring as your filly but with hardly any stripping (but dose have some). He is a double bred King Supreme son that is a smutty roan and has a dorsal srtip as well. The weird thing about his color is that it's all mixed up through-out his body but has the dark legs. If someone could post a photo for me to show you his uniqe color, I'll show you. Otherwise I am very facinated about this fillys color as she is breathtaking!
It is all just so fascinating and exciting!!
