Lors du croisement de deux plants de pois de race pure, la plante A et la plante B, la progéniture de la génération F1 ne présente pas le phénotype de la plante A, mais ce phénotype réapparaît dans la génération F2. Laquelle des plantes, A ou B, est grande et laquelle est naine ?<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>
