What is the proportion of double recessive offspring in the F_2 generation in a mendelian dihybrid cross?

In a monohybrid cross between tall pea plants (TT) and short pea plants (tt) a scientist obtained only tall pea plants (Tt) in the F_(1) generation. However, on selfing the F_(1) generation pea plants, he obtained both tall and short plants in F_(2) generation. On the basis of above observations with other angiosperms also, can the scientist arrive at a law? If yes, explain the law. If not, give justification for your answer.

In the F_2 generation of a Mendelian dihybrid cross the number of phenotypes and genotypes are :
