Name: Ashanti Reign V. Tabalba Section: 9-Euler

This document discusses blood type inheritance through Punnett squares. It shows that if a father is type B and the mother is type O, their baby will be type B based on a Punnett square with a 100% phenotypic ratio of B. It also shows the possible blood types if a mother is type O and a father is type AB, which results in a 50% chance each of types A and B based on another Punnett square.
