What are the possible parental bloodtypes for a child with the blood-type A positive?

Answer 1

There are many possibilities, but two things are certain: at least one parent must be type A or AB, and at least one parent must be Rh +

A child with blood type A+ can have the following combinations of parents:

Mother A+, Father A+

Mother A+, Father A-

Mother A-, Father A+

Mother A+, Father B+

Mother A+, Father B-

Mother A-, Father B+

Mother A+, Father AB+

Mother A+, Father AB-

Mother A-, Father AB+

Mother A+, Father O+

Mother A+, Father O-

Mother A-, Father O+

Mother B+, Father A+

Mother B+, Father A-

Mother B-, Father A+

Mother B+, Father AB+

Mother B+, Father AB-

Mother B-, Father AB+

Mother AB+, Father A+

Mother AB+, Father A-

Mother AB-, Father A+

Mother AB+, Father B+

Mother AB+, Father B-

Mother AB-, Father B+

Mother AB+, Father AB+

Mother AB+, Father AB-

Mother AB-, Father AB+

Mother AB+, Father O+

Mother AB+, Father O-

Mother AB-, Father O+

Mother O+, Father A+

Mother O+, Father A-

Mother O-, Father A+

Mother O+, Father AB+

Mother O+, Father AB-

Mother O-, Father AB+

Answer 2

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

Parental information:

• Mother type A pos -- can be AA or AO and Rh (++) or (+-)
• Genes: A, O, (+), (-)
• Father type A pos -- can be AA or AO and Rh (++) or (+-)
• Genes: A, O, (+), (-)

Baby receives one gene from each parent:

• Baby is type AA + (++) = Type A pos
• Baby is type AA + (+-) = Type A pos
• Baby is type AA + (--) = Type A NEG
• Baby is type AO + (++) = Type A pos
• Baby is type AO + (+-) = Type A pos
• Baby is type AO + (--) = Type A NEG
• Baby is type OO + (++) = Type O pos
• Baby is type OO + (+-) = Type O pos
• Baby is type OO + (--) = Type O NEG

YES, the baby of two Type A+ parents can be Type O+.

Answer 3

For a child to be B :

Both parents are B

one B and the other O

One B and the other A

one AB and the other A

one AB and the other B

one AB and the other O

For a child to be positive :

Both parents are +

or one negative and the other positive.

Medical Answers need to be confirmed and re-confirmed.

Answer 4

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

Available information:

• Mother type O pos -- can only be OO with Rh (++) or (+-) = contributes O, (+), (-) genes
• Father and Baby unknown

Baby receives one gene from each parent:

Note: easy assumption is that the baby will be either Rh positive or Rh negative.

• Mom type OO + Dad type AA/AO = Baby type AO, OO pos/neg
• Mom type OO + Dad type BB/BO = Baby type BO, OO pos/neg
• Mom type OO + Dad type AB = Baby type AO, BO pos/neg
• Mom type OO + Dad type OO = BAby type OO pos/neg

Generally Mom can only contribute her O gene to the baby, the baby will have to be either AO, BO or OO.

HOWEVER: There is more to ABO blood typing that just the ABO gene.

There is also an inhibitory gene that will change any genotype into the phenotype O.

Therefore a person with genetically AB blood can be tested as having Type O.

If the Type O mom has the inhibitory gene affecting her Type A, B or AB blood,

then the Type AB baby is definitely possible.

Answer 5

Most ljkely O positive.

Answer 6

you are O2 squared
