$\huge\bold{\textbf{\textsf{{\color{cyan}{Answer}}}}}$

∴ Back Cross

The genotypes TT and Tt both produce a tall phenotype. In order to establish the genotype, a test cross is used. The organism in question is crossed with a homozygous recessive individual (tt). If no short plants (tt) are produced in the offspring the unknown parent was homozygous (TT).

∴ Test Cross

The crossing of an F11 progeny with a double (homozygous) recessive parental progeny is done in order to determine whether the progeny is homozygous or heterozygous for a character under consideration. This is called as test cross.
