Question

What logical sequence step immediately follows the observation that all F₁ offspring were tall when TT was crossed with tt?

पर्याय

• Concluding that the dwarf trait is completely eliminated

• Recognizing that the tall allele dominates over the dwarf allele

• Determining that both parents have the same genotype

• Predicting that F₂ will be all dwarf

Answer 1

The observation that all F₁ are tall leads to the inference that the tall allele (T) dominates over the dwarf allele (t). This is the direct logical inference from observing uniform tall phenotype in F₁ hybrids.
