It all depends. If you are for example homozygote AA and you don't marry someone blood type B, the A phenotype will be passed on. But if there is a B coupling with a recessive O, then the A will be "lost".I am A+ Blood Group, as is my father, my brother and my son, Is it possible for one blood group to stay in generations of a persons single Y-Haplogroup or mtDNA haplogroup
Facts including Inheritance etc:
https://www.disabled-world.com/calculators-charts/blood-chart.php
When one parent carries a Cis AB allele, the other allele can be any of O, A or B and the phenotype of this parent is always AB, but the children will inherit either the AB or the other allele from this parent.
(Caution: ABO inheritance is generally derived assuming the children are not the very rare Bombay phenotype which would require both parents to be carriers of it.)
- If the other parent is O phenotype (OO genotype) there are three possible scenarios for the blood group of children of a Cis AB carrier (and a 4th very unlikely scenario):
- The second allele is O: children are either AB or O
- Second allele is A: Children are either AB or A
- Second allele is B: Children are either AB or B
- A very rare 4th possibility exists: if the other allele is also Cis AB then the children will be always AB irrespective whatever the other parent is, because they will have one cis AB allele from this parent.
- If the other parent is type A, depending on whether this parent is genotypically AA or AO and what the other allele is in the Cis Ab carrying parent, the following scenarios are possible:
- Other parent is AO and second allele is O: The children are either AB or A or O
- Other parent is AA and the second allele is O: The children are either AB or A
- Other parent is AO and second allele is A: The children are either AB or A
- Other parent is AA and the second allele is A: The children are either AB or A
- Other parent is AO and the second allele is B: The children are either AB or B
- Other parent is AA and the second allele is B: The children are always AB
- Rare situation: If the other allele is also cis AB:The children are always AB
- Likewise, there will be similar scenarios for the other parent being type B:
- Other parent is BO and second allele is O: The children are either AB or B or O
- Other parent is BO and second allele is A: The children are either AB or A
- Other parent is BO and the second allele is B: The children are always AB or B
- Other parent is BB and the second allele is B: The children are either AB or B
- Other parent is BB and the second allele is O: The children are either AB or B
- Other parent is BB and the second allele is A: The children are always AB
- Rare situation: If the other allele is also cis AB:The children are always AB
Which app?How do you determine whether its Rh+ or Rh-? The app does not seem to specify.
Im B-, Seems to be more common in East Asia, but had some hot spots in Central Europe. All in all, I wouldent put to much into it. Its like Haplogroups, just a part of the puzzle.
Very interesting. Thanks for posting, Tomenable.
The role of Rh+ is still unclear but it has been linked to protection against toxoplasmosis (passed on by cats). So cat lovers had better be Rh+.
Interesting. I have worked with Prof. Flegr on this study:[/I]If I understand correctly Rh negative individuals due to their better psychomotor performance had a distinct advantage in hand to hand combats and in warrior societies. Hence the high incidents of Rh- among Yamnaya people could have helped them conquer the neolithic farmers ( who were largely Rh positive).

Do you have any more data on the Yamnaya people being high in rh negative blood? Would love to look at it.
Тhat is the paradox - Rh- people have numerous health problems compared to Rh+, but this harmful mutation is still widely spread. The conclusion is that it must have some unknown benefits, which the study with toxoplasma link is trying to explain.
I find your mtDNA interesting. Close to:My dad being negative is the only oddity in the family, as everyone else is O positive. But then we've got a lot of Irish blood; it's the only ancestry my mother and father have in common. With my dad being the universal donor, he gave blood a lot when I was a kid.
