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

Parental information:

  • Mother type O --can only be OO = contributes the O gene
  • Father type AB --can only be AB = contributes A and B genes
Baby receives one gene from each parent:
  • Baby is type AO = Type A
  • Baby is type BO = Type B
Generally speaking, with these parents there would be a 50% chance of either having a Type A or Type B baby.

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 parent has the inhibitory gene affecting his Type A, B or AB blood, then other blood types for the baby are possible.

How are Punnett squares used to predict the possible blood types of offspring in a genetic cross involving parents with different blood types?

Punnett squares are used to predict the possible blood types of offspring in a genetic cross involving parents with different blood types by showing all the possible combinations of alleles that the parents can pass on to their offspring. This helps determine the likelihood of each blood type in the offspring based on the parents' genotypes.


How can one create a Punnett square to determine the possible blood types of offspring based on the parents' blood types?

To create a Punnett square for determining the possible blood types of offspring based on the parents' blood types, you would first identify the blood type alleles of each parent (A, B, or O). Then, you would create a 4-square grid with the alleles of each parent on the top and side of the grid. By combining the alleles in each square, you can determine the possible blood types of the offspring.


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.


How can Punnett squares be used to predict the potential blood types of offspring in a genetic cross?

Punnett squares can be used to predict the potential blood types of offspring in a genetic cross by showing the possible combinations of alleles from the parents. By filling in the squares with the parents' blood type alleles (A, B, or O), you can determine the likelihood of each blood type for the offspring.


If male has type a and female has type ab what are the possible blood types of their offspring?

The blood type will be the same as one of the parents or a combination, so A or AB. If the parents both have the same Rh factor (+ or -) the baby will have that factor, else it could also be either. The risky situation at birth is where the baby's Rh factor is not the same as the mother's.

Can you tell if a kid is yours by parents blood type if the fathers have different?

Certain blood types are not obtainable in offspring when the parents have certain blood types.

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.


What blood type (or types) can be found in an offspring if a mother has A blood and the father has type B blood?

Without any further information about the blood types of the offspring's parents, you can say that the offspring of a parent with type A and parent of type B could have any blood type -- A, B, O, or AB.
