Transcribed Image Text:Miscanthus is a grass that grows rapidly and is used in biofuels research.
Two true-breeding strains, of the 90 cm and 100 cm classes, are crossed. All of the F₁ offspring
belong to the 95 cm class. An F₁xF₁ cross results in wide variety of height classes. The
distribution of members of F2 generation are displayed on the following histogram:
