In the p generation, a tall plant was crossed with a short plant. the short plants reappeared in the f1 generation because ?

In the F1 he genotype was Tt and T is dominant tall and t is recessive short and so they were all tall. 

In the F2 the genotypes are TT Tt Tt tt since the gametes are T and t. 

One short (tt) to three tall (TT Tt Tt)

Ithink the answer is true

Ijust took the test on edgenuity and the answer is "life would cease to exist". hope this !
