Problem 29: Integrating Inheritance & Molecular Effects

Hard
Dihybrid CrossMutationIntegration

In a plant, gene A controls flower color (A=red, a=white) and gene B controls height (B=tall, b=short). They assort independently. A plant heterozygous for both traits (AaBb) is crossed with a white, short plant (aabb). A common nonsense mutation exists for gene A. What is the probability that an offspring will be phenotypically white and tall?
