In pea plants, tall plants are dominant over short, and green pods are dominant over yellow. If you crossed true- breeding tall, green- podded plants with true- breeding short, yellow- podded plants, and then crossed the F1 individuals among themselves, what proportion of the F2 offspring would you expect to be tall and yellow- podded?

Question

Quizplus · Accepted Answer

The F1 generation would all be heterozygous tall and green-podded. In the F2 generation, the probability of being tall (T_) is 3/4 and yellow-podded (yy) is 1/4. Multiplying these probabilities gives 3/16.
