I’m AB negative, which, I believe, make makes one of my earliest ancestors a Neanderthal—though I find Denisovans even more interesting.

Also, I’m a universal donor. Friend who volunteered at the blood bank told me to never give blood or they’d drain me dry.

O- is the universal donor blood. You’d be the universal receiver.

Are you trying to kill me, an O- bloodtype?|

Scientists also wonder if RHO- bloodtypes have an alien origin.

No.

You cannot give blood to anyone except AB. ( + or - ).

You can accept blood only from AB-.

This is the rarest of blood types.

It’s also mine.

When I was first married my employer had a blood drive. I decided to donate and they took my blood and gave me a card with my blood type on it. It was B. When I told my hubby that, he said that it had to be B positive because B negative was very rare. Well, it was, and is, B negative. And after I did that the blood drive people were calling me constantly to give more blood.

I wouldn't mind giving blood; but, finding my veins are a real problem. Finally, after years of having people search for a vein to tap some blood for a test, the last tech I went to did find my vein and told me that it was there; but, it was very deep.

I know the genetic testing services provide % of Neanderthal genes. Do they do Denisovan genes now too? My mother’s family was Prussian, and my father’s British. I probably have some far eastern (Asian?) blood because eastern Europe was attacked by Mongols and others. My 2 lateral incisors have the shovel shape that Neanderthal teeth have. I wonder if Denisovan teeth also have that marker? My husband had light blue eyes, and mine were hazel. Both our sons have dark brown eyes. The only way I can figure it is that I must have dark brown recessive eye genes (probably far eastern) that were less recessive than my husbands very recessive blue eyes.

AB negative is the universal PLASMA donor - not the universal blood donor.
