RH negative factor

The Neanderthal theory for negative HR does not make any sense. In East Asia there is more Neanderthal mix than in Europe and there is no negative HR factor there

You refer to "the Neanderthals". Neanderthals may have been more diverse than modern humans. Though I see no evidence of Rh(D) negative presence in any of their groups, it is entirely possible for some to have been Rh(D) positive and others negative.

Father o - like his mom

The negetive factor is found in basque

Im B Neg. I think that is strange for me because I have ancestry from all over Europe. If it was all localized and my ancestors were in a single hot spot it would make sense, but thats not the case.

Not that strange. Rh positive homozygotes are in the minority in Europe.
As for B:
Technically speaking, all it takes is one B ancestor generations ago.

Blood group B has its highest frequency in South Asia where it ranks first as the largest share of the earth's population. In Southeast Asia the share of the population is high, especially in Thailand and Indonesia, then in East Asia, Northern Asia and neighboring Central Asia, and its incidence diminishes both towards the east and the west, falling to single digit percentages in Netherlands, Norway, Portugal and Switzerland.^[44]^[45] It is believed to have been entirely absent from Native American and Australian Aboriginal populations prior to the arrival of Europeans in those areas.^[45]^[46]
Blood group A is associated with high frequencies in Europe, especially in Scandinavia and Central Europe, although its highest frequencies occur in some Australian Aboriginal populations and the Blackfoot Indians of Montana, the US.^[47]^{[48]

I have recently posted that Poland has 19.67% rh negatives. Looking at national frequencies is important, but since nations can be quite genetically diverse, looking at regional data has proven to be even more informative. Due to my own ancestry, Silesia has been of great interest to me in terms of where the rh negative blood in my own family might come from.
The following study from 2017 will reveal that Lower Silesia has the highest frequency of rh negative people in all of Poland and also the highest frequency of blood type O. 21.1% rh negatives among women and 19.2% rh negatives among men. This is a huge difference between male and female data which needs to be further examined. Both, rh negative and blood type O frequencies have been decreasing drastically.

More than half of Northern Ireland is blood type O. More than 27% RH Negative.

As for when the deletion ocurred, a curiosity is that these variations may be observed in primates.

"Chimpanzees have been found thus far to have primarily type A blood, with type O less commonly. Gorillas appear to be exclusively type B. Orangutans express all three blood types."
https://carta.anthropogeny.org/moca/...and-prevalence
Monkey Rhesus would be exclusively B, as Gorillas.

I guess the prevalence of one over the others may be sometimes related to environment/selection (as possibly RH- in Steppe?).

As for blood type in my family, in theory my parents, as AO, would have 25% of chances of having an AA child, but I'm AO after all, according to 23andMe Raw Data. My parents and my siblings are all RH+, as myself, my wife (O+) and my son (A+). However, my O+ brother has an O- daughter, which means that he's heterozygous. The odds are that just one of my parents is RH heterozygous, since they had 5 children, and all RH+.

Reply: Me: A RH+. My wife: A RH-. My son: A RH-. My mother: A RH+. My father: O RH+.

Reply: Yes. Conclusion: I am heterozygous in the RH factor and I am heterozygous in the ABO classification system. This means that I am more healthy? I don’t Know
But, in fact, I am a healthy person, thanks God.

ABO wise it depends. As I have posted above, when it comes to COVID-19, malaria and a few others, being phenotype A may carry some disadvantages.

By the way:

In European populations Rh positive heterozygotes seem most frequent over rh negative and rh positive homozygotes.

Reply: Dear Regio X,
Maybe my dad is a point off the curve, then. Intelligent, politicized, cultured, a great classical music lover, he gave me classes in public accounting and balance sheet analysis, when I knew nothing about it, providing me with a wide range of books and preparing exercises to train me. I owe a big part of my personal and professional success to him. He retired and remained a great devourer of books and newspapers. Sometimes I had a hard time keeping up with his quick thinking. At 80 he was diagnosed with Alzheimer's disease. At 84 he was admitted, when his brain could no longer control even his breathing. He died after 3 months in an ICU. I am flattered when the paternal and maternal family members say that I am the son who most resembles him physically: “The father's features and the mother's skin tone”. He was blood type O, factor RH +. According to the doctor, he resisted because he was a strong man with a healthy heart, who insisted on continuing to beat. My biggest fear: Having Alzheimer and dying the same way he died
Cheers

Good idea. Since it connects to COVID-19 and rh negative blood, here again is my post connecting the both:
COVID-19 deaths: 1 out of 45 Rh- and 1 out of 8 Rh+ patients (NYP/CUIMC)

Among the patients with Rh(D) positive blood groups, 1 in 8 died.
Among the patients with Rh(D) negative blood groups, 1 in 45 died.

RH negative factor
