How do I find out what my Mom's blood type was? She is deceased and I'm trying to find my paternal father.
If you have access to your burth records and your mother's medical records the information might be located their.Also I work on my family tree and many of us did the DNA test. This eill be a posdible wY to connect to your parental side of your family. It is a great tool. I used ancestry dna test.
How can I find my Mom's blood type? She's deceased.
There are a few options.You could try to get a copy of her medical records. They may have her blood type, particularly if they were from a hospital.If she was in the military, they would have a record.If you have a sample of her DNA (hair with follicle attached, blood, etc.) you could find a lab that would test her DNA and tell you her blood type. This would probably be expensive.If you have living blood relatives of hers, you could find out their blood types and, in combination with your blood type and that of your siblings, you could work out her most probable blood type. For example, one sibling and I are O positive, and two of my siblings are A positive. Therefore, one of our parents was an O and one was an A; most probably they were both Rh positive.
My mom has blood type AB+ and my father has blood type O+. But mine is O+. How is it possible?
Hey there!So far the combination of allels in blood grouping is concerned,Your mom’s allels in gametes: IA+ or IB+Your dad's allels in gametes: i+ only.You should have: IAi+ or IBi+ (A+ or B+)consider rechecking blood groups of yours as well as of your parents.
Whats my blood type if my mom is b+ and my dad is O?
50/50 chance child being B or O No chance of A or AB If Both parents are Rh + (you say Mom B+ but ??? Dad) then childs blood group will be B+ or O+
If a father has an O blood type and a mother has an AB blood type, what will be the child’s blood type?
It would be either A or B blood group.As the father has O blood group( recessive and is expressed only if present in homozygous condition) so possible alleles are O and O.The mother has AB blood group, which means the possible alleles would be A and B.Thus, the child may either have AO gene pair (2 alleles make one gene pair) or BO gene pair. This implies that either the child would have A or B blood group as I mentioned earlier too that O is recessive and is expressed only in homozygous condition. And here the resultant being heterozygous i.e., AO and BO, O would not be expressed.Thank you
My father is blood type AB- and my mother is O+, so what is my blood type most likely to be, and can it be O+?
EDIT - Doris Studnicka in the comments has enlightened me about a rare mutation called Cis AB - which could, in your scenario, end with you having O blood. More information at that Wikipedia link!No.You receive one allele from each parent for type so from your father you could get an A- or a B- and from your mother you would get an O+ or an O-So your possible blood type could either be A or B and your Rh factor either positive or negative:A- and O+ = A+A- and O- = A-B- and O+ = B+B- and O- = B-For “O” type blood, you need to get an “O” allele from both parents, which is impossible if your father is blood type AB.
My blood type is O+ & my dad is O-. I'm unsure of my Mom's blood type, she passed 10 years ago. Could my dad not be my biological father?
Blood typing is not a conclusive evidence for confirming parentage.There are more than 160 known blood types, not four.For a child to be O+, with one parent as O-, the possibilities in simple terms are as follows.O-ve (OO-) and O+ve (OO+) =child O +veO-ve and A+ve (AO+) = child O+ or A+O-ve and B+ve (BO+) = child O+ or B +Your mom could have been O, A or B positive and you'd still have O positive with your father's O negative (Rh negative gene is recessive, positive is dominant. So you are technically hiding your dad's Rh negative genes, that could get expressed in a future generation.)If you marry a person with positive blood type, it's still possible for you to get a (totally legitimate) negative blood type kid (your dad's gene and your spouse's similar hiding negative gene).If I have managed to cause enough confusion with my genetics explanation, please feel free to comment and I will try to simplify this to plain English .Update. I noticed some comments which seem to be from the OP, and it seems a bit more serious than just a doubt of paternity. So here's a link that could help you.Disclaimer.

Blood type: Can an AB man has an O child?
No, a man with type AB blood can NOT have a type O child... The way blood types work is that A and B are surface markers on the red blood cells that are inherited. Type O means that there are NO surface markers. A and B types are codominant (i.e., both dominant) over type O. So...if your father has an AB blood type, your brother MUST be either A or B or AB for this man to be his genetic father...he can NOT be O, no matter what your mother's blood type is. The genetics are thus: If Dad is AB and Mom is O: the possibilities for the children are AO or BO (type A or type B). If Dad is AB and Mom is A: possibilities are A, B or AB. If Dad is AB and Mom is B: possibilities are A, B or AB. If Dad is AB and Mom is AB: possbilities are A, B, or AB. P.S.--Just because it's not possible for your father and brother to be related, that doesn't necessarily imply that your mother is a bad person...it just means she made a serious mistake in being unfaithful. Don't let that influence your love for your brother.
Why my blood group is O negative as my mom blood group is B positive and my father's is O positive?
Blood group is an example of multiple allelism. Blood group decides by three type of genes:-1st is responsible for A antigen2nd is for B antigenThird has no type of antigen.For every blood group gene, it has two different alleles. In your condition your mother has B+ blood group with two alleles:- dominant B and recessive O. She also has Rh+ and Rh- antigen. And your father has O+ blood group with both O alleles. He also has Both Rh+ alleles. According to Mendal’s law of dominance your mother and father have the dominant trat in their blood group.And you has O- blood group. You have both recessive O alleles for your blood group. You got Both O antigen from your parents. And according to me you have not got the Rh factor from mother. But you must got a Rh factor from your father.But how you have not the Rh antigen? Check your blood group and your father blood group again in term of Rh factor. If you are right in your information than it might be depends on your mother’s mitochondria. It is possible . It calls maternal heredity.Don't worry friend.Thanks☺
