What blood types would the offspring of a parent with AB and other Ao be?

If one parent has AB blood type (A and B alleles) and the other parent has AO blood type (A allele and O allele), the possible blood types of their offspring are A, B, and AB.

Here's the Punnett square that shows the possible combinations of alleles inherited from the parents:

| | A | B |

|---|---|---|

| O | AO | BO |

| A | AA | AB |

As you can see from the Punnett square, the offspring can inherit either the A allele, the B allele, or both (AB genotype) from the AB parent. The offspring can inherit either the A allele or the O allele from the AO parent.

Therefore, the possible blood types of the offspring are:

- A: If the offspring inherits the A allele from the AB parent and the A allele from the AO parent.

- B: If the offspring inherits the B allele from the AB parent and the O allele from the AO parent.

- AB: If the offspring inherits the A allele and the B allele from the AB parent.

It's important to note that the probability of each blood type occurring depends on the frequency of the alleles in the population. In general, the ABO blood group system is inherited in a Mendelian pattern.
