Researchers found a pair of boy girl twins that shared about 90 percent of their genes calling them ‘ semi identical “. That is just fascinating to me and I thought I’d share

Interesting.
That is fascinating.
I followed one of the click-bait links at the bottom of that story and learned about another interesting genetic phenomenon, that of the Chimera (the baby’s DNA didn’t match the mother’s DNA, because the mother actually had two sets of DNA…). Apparently this could occur if the mother herself (the chimera) was born from an embryo that was originally one of a pair of fraternal twin embryos that combined to form a single embryo.
Here’s a Scientific American link on it: https://www.scientificamerican.com/article/3-human-chimeras-that-already-exist/
(not the same clickbait story that I followed, but the case of Karen Keegan discussed in this article was mentioned in that piece)
