Short pea plants exist in the P1 and F2 generations. What happens to the phenotype in the F1 generation?

The allele for short pea plants is absent from the genotypes in the F1 generation.

The allele for short pea plants is masked during the F1 generation, but it is still present in the genotype.

The allele for short pea plants is not passed on to the F1 generation.
A short and tall pea plant exist in the P 1 generation. The F 1 generation includes all tall pea plants. The F 2 generation has 3 tall and 1 short pea plant.

Correct choice: "The allele for short pea plants is masked during the F1 generation, but it is still present in the genotype."

Explanation: This is the classic Mendelian pattern with tall dominant (T) and short recessive (t). P1: TT (tall) × tt (short) → F1 all Tt (heterozygous) and phenotypically tall because T is dominant. When F1s (Tt × Tt) are selfed, F2 genotypes are 1 TT : 2 Tt : 1 tt, giving a 3 tall : 1 short phenotype ratio, so the short allele reappears.
