Question

parents with the genotypes ao and ab have a child. what are all the possible blood types of the child?
a, b
o, ab
a, ab, b
o, ab, a

Explanation:

Step1: Determine possible alleles from each parent

Parent 1 (AO) can pass on A or O alleles. Parent 2 (AB) can pass on A or B alleles.

Step2: Create Punnett square combinations

• A (from Parent 1) and A (from Parent 2): Genotype AA (Blood type A)
• A (from Parent 1) and B (from Parent 2): Genotype AB (Blood type AB)
• O (from Parent 1) and A (from Parent 2): Genotype AO (Blood type A)
• O (from Parent 1) and B (from Parent 2): Genotype BO (Blood type B)

Step3: Identify possible blood types

From the combinations, the possible blood types are A, AB, and B.

Answer:

A, AB, B (the third option: A, AB, B)
