April 14, 2022- This evening, I saw a snippet of a drama, discussing the curious matter of blood type chimerism, in which a person could have more than one blood type. The matter is explained in detail, in: https://pubmed.ncbi.nlm.nih.gov/17053463/ and https://www.healthline.com/health/chimerism.
This issue is raised, when a child has a blood type, which neither parent of record is known to have. Each parent may then be tested for chimerism, in the hopes that nothing skeevy has gone on and resulted in the child having been sired by a third party. Of course, this matter can be complicated by in vitro fertilization, sperm or egg donors, or just a series of multiple partners, prior to the pregnancy and birth.
I am old school, when it comes to such matters. I fell in love and married, once, and did not stray. There was never any doubt, as to our son’s parentage, as there is no doubt in probably 90% of all childbirths-even those which are “unwanted”. Ours was very much wanted, of course, and any grandchildren I may have will enjoy the same welcome from their parents.
Blood can be a simple thing. It’s the emotional aspect that makes matters of the heart get complicated. This also is true of relationships between extended families, communities and nations. We have only to get back to the very basic awareness that all bleed red, and are one human race.

My sister’s eldest is a chimera – she absorbed her twin! So she has patches of skin that are a different color…

Amazing story. I hope she has done well in life.

That’s cool. Does it affect her health? If not, it’s just what makes her unique. I’ve seen other people with different patches of skin… Does anything else cause that trait? I don’t know.

That’s strange. I don’t have the rh problem, or whatever, but my blood is A+ and my mom’s is O+. It caused me to be jaundice, I suppose. The family also said that her body attacked me. However, the real reason I was born 6 weeks early was because a doctor stuck his hand up my mom without gloves.

Stranger things have happened. Those were certainly the days. I have never been told the full story of my own birth-just that I was “almost breech”.

That stinks. Yeah, weird things have happened to people, bizarre things. Sometimes people end up with stone babies that they carry for decades.

I feel horrible for the women who endure such a tragic event.
