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
