Question

What are the phenotype and genotype of all offspring produced by \[TT \times tt\]?

Options

• Dwarf with genotype \[tt\]

• Tall and dwarf with genotypes \[TT\] and \[tt\]

• Tall with genotype \[Tt\]

• Tall with genotype \[TT\]

Answer 1

Each offspring receives \[T\] from the pure tall plant and \[t\] from the pure dwarf plant. Therefore, all F1 offspring are tall with genotype \[Tt\].
