There are very few AB negatives on earth, depending on nationality of course. Or rather: Heritage. When looking at people who are AB negative, it is more or less reasonable to look at personalities for people who are blood type A, blood type B and sort of imagine a mix.
In addition, while most A and B people are genotype wise AO and BO, AB people do not carry the O allele recessively unless their are cisAB/O.
Are you blood type AB?
Please read up on A Negative Blood and People and B Negative Blood and People and let me know which you can identify more.
Looking forward to your feedback!
