We are looking for the possible blood types of a baby.

Available information:

  • Baby type A neg -- this may be AA or AO with Rh (--)
  • ABO: must receive A gene from at least one parent
  • Rh: must receive Rh (-) gene from both parents
Baby receives one gene from each parent:

Note: parents can be Rh (++) or (+-), but we know baby gets (-) from each.

  • Mom AA/AO + Dad AA/AO = Baby Type AA, AO, OO
  • Mom AA/AO + Dad BB/BO = Baby Type AO, AB
  • Mom AA/AO + Dad AB = Baby Type AA, AO, AB, BO
  • Mom AA/AO + Dad OO = Baby Typw AO, OO
  • Mom AB + Dad BO = Baby Type AO, BB, BO
  • Mom AB + Dad AB = Baby Type AA, AB, BB
  • Mom AB + Dad OO = Baby Type AO, BO
There are a lot of combinations for the parents of an A neg baby. To narrow it down, if the parents are not available, then a survey of the blood types of the grandparents would be the next step.

What is the likelihood of a child's blood type being determined by the blood types of their parents?

The likelihood of a child's blood type being determined by the blood types of their parents is high, as blood type inheritance follows specific patterns based on the parents' blood types.


How do you find out what blood type you are if your parents' blood types are O and A?

It's simple ask your Doctor for a "blood type" blood test. If your doctor has ever done blood work on you, he might have your type on file already!


How can one determine blood type from parents?

Blood type can be determined from parents by looking at their blood types and using the principles of genetics. A child's blood type is determined by the combination of blood type genes inherited from their parents. For example, if both parents have type A blood, their child could have either type A or type O blood. If one parent has type A blood and the other has type B blood, their child could have type A, type B, type AB, or type O blood.


Possible blood types of offspring?

Offspring can inherit blood type from their parents based on their genotypes. Possible blood types include A, B, AB, and O. A child's blood type will be determined by the combination of blood type alleles inherited from their parents.


Are all children of same parents the same blood type?

of course they can, it doesnt mean that if you dont have the same blood type as your siblings, your adopted or something. if your parent's blood types differ from each other there is a huge tendency that the sibling's blood types are different from each other. for exaple your father is a heterozygous A while your mother is a heterozygous B.. their children's blood types can be AB, and an O can also be one of the possiblities.. if its too complicated to understand then you can just learn it from your genetic lessons in biology..

Are daughter and father blood types the same?

Not necessarily. The blood type of a child is determined by the combination of the parents' blood types. It is possible for a daughter to have a different blood type than her father, depending on the specific blood type alleles inherited from both parents.

Can a parent with ab plus and the other parent with o plus have a child with o plus?

Yes, it is possible for two parents, one with AB+ blood type and the other with O+ blood type, to have a child with O+ blood type. When two parents with different blood types have a child, the child's blood type can be a combination of the parents' blood types through genetic inheritance.


What some have o blood type where both parents are AB and B?

It is not possible for two parents with blood types AB and B to have a child with O blood type. A child's blood type is determined by the combination of their parents' genes, and O blood type requires both parents to have at least one O gene.


What are blood types that are possible to have?

The blood types are A, B, AB and O. Rh positive or negative are also blood types possible. What blood type we will have is inherited from our parents.
