Final answer:
The genotypes and phenotypes of the parents, possible gametes, Punnett square, and F1 genotypic and phenotypic ratios are filled in for a child with type O blood born to a mother with type A blood and a father with type B blood.
Step-by-step explanation:
The parents' genotypes are IAi for the mother (type A blood) and IBi for the father (type B blood).
The parents' phenotypes are A for the mother and B for the father.
The possible gametes for the mother are IA and i, while for the father they are IB and i.
The Punnett square would show 4 possible combinations: IAIB, IAi, IBi, and ii.
The F1 genotypic ratio would be 1 IAIB : 2 IAi : 2 IBi : 1 ii.
The F1 phenotypic ratio would be 2 A : 2 B.
