Al cruzar dos plantas de guisantes de raza pura, la Planta A y la Planta B, la descendencia de la generación F1 no muestra el fenotipo de la Planta A, pero este fenotipo reaparece en la generación F2. ¿Cuál de las plantas, A o B, es alta y cuál es enana?<end_of_turn>
<start_of_turn>model
Plant A is dwarf, and Plant B is tall.

Here's the reasoning:

If plants that look like A don't appear in the F1 generation but re-emerge in the F2 generation, it means that the trait of plant A is recessive. In classic pea plant experiments, tallness is a dominant trait while dwarfness is a recessive trait. Therefore, in this case, Plant A must be dwarf and Plant B must be tall. 

In the F1 generation, all plants would exhibit the dominant trait (tallness). In the F2 generation, the recessive trait (dwarfness) re-emerges in a 1:3 ratio (dwarf:tall) if two heterozygous tall plants from F1 are crossed.<end_of_turn><eos>
