      To produce a short recessive pea plant (tt), we need at least one parent to provide the recessive allele (t). Let’s analyze the combinations:

      1. TT x TT – All offspring will be TT (tall). No tt.
      2. Tt x tt – Offspring can be Tt (tall) or tt (short). This combination works.
      3. tt x tt – All offspring will be tt (short). This combination works.
      4. TT x tt – Offspring will be Tt (tall). No tt.
      5. Tt x Tt – Offspring can be TT (tall), Tt (tall), or tt (short). This combination works.

      Correct parental combinations producing tt:

      – Tt x tt

      – tt x tt

      – Tt x Tt

      In summary, for a short recessive plant (tt) to occur, at least one parent must contribute a recessive allele (t).
