Question

Quizplus · Accepted Answer

The possible genotypes of the offspring are Tt and tt. Only Tt plants are tall. The probability of an offspring plant being Tt is ½. The probability of every single one of the six offspring plants being Tt can be calculated using the product rule. Probability of ½ and ½ and ½ and ½ and ½ and ½ and ½ = ½ x ½ x ½ x ½ x ½ x ½ = 1/2⁶ = 1/64
