Two heterozygous tall pea plants (Tt × Tt) produce three offspring. What is the probability that all three are tall?

Correct answer D. 27/64

Explanation

P(tall) = 3/4 for each offspring; for three independent offspring, (3/4)³ = 27/64. Each birth is an independent event, so the probabilities are multiplied together.
