reappears in some plants in the F2 generation
In Mendel's experiments, the recessive traits were observed in the F2 generation. Initially, the traits were not visible in the F1 generation, where only the dominant traits were expressed. However, when the F1 plants were allowed to self-pollinate, the recessive traits reappeared in the F2 generation, typically in a ratio of about 3:1, dominant to recessive.

50% because it divided half to
he breeded the f1 plants with a recessive homozygous plant and if the offspring (f2) showed the recessive allele, then the recessive allele is still present in the f1 plant

The reason why short plants reappeared in Mendel's F2 generation of pea plants was because their short trait was heterozygous. Both parents carriedÊthat recessive gene, so they passed it on to their offspring.
