Final answer:
To complete the Punnett square for the blood types of the offspring produced by a type 'O' mother and a type 'AB' father, we get four possibilities: AO, BO, AO, and BO, with 25% chance for each blood type.
Step-by-step explanation:
To complete the Punnett square for the blood types of the offspring produced by a type 'O' mother and a type 'AB' father, we need to consider the alleles for the ABO blood groups. The mother has two copies of the 'O' allele (ii), and the father has the 'A' and 'B' alleles (IAIB). When we cross these alleles on a Punnett square, we get four possibilities: AO, BO, AO, and BO. So, all the possible blood types of the offspring are A, B, A, and B. The percentages of each offspring are 25% for each blood type.
