Regarding this, Is TT purebred or hybrid?

In the first of Mendel's experiments, a tall purebred pea plant (TT) was crossed with a short purebred pea plant (tt). The result of this cross was all tall hybrid pea plants (Tt).

Then, What is an example of a purebred allele?. For example, the gene that controls height in pea plants has one allele for tall height and one for short height. An offspring inherits two alleles for each trait. ... An organism that has two identical (same) alleles for a trait is called a purebred.

Subsequently, question is, Is FF a purebred?
