) A florist obtained a prize winning flower that he wants to breed to be sold. The trait that makes his flower stand out is dominant for a particular trait. In order to successfully breed this flower, he needs to make sure that the dominant trait is pure dominant and not a hybrid. What should the florist do to determine whether or not the flower is pure or hybrid for this trait?

A test cross is a cross that is made between an organism with an unknown dominant genotype and an organism that purebred recessive genotype for the particular trait. It determines if the unknown genotype of the individual being tested is purebred allele dominant or heterozygous for the trait.

If all offspring in F1 generation has phenotypically dominant trait then the tested organism is pure breed dominant and if half of the offsprings have the phenotypically dominant trait and half show recessive trait then the organism to be tested is heterozygous or hybrid.

The florist will test cross whether or not the flower is pure or hybrid for this trait.

A test cross would be a hybrid between this and an individual with nothing but an undiscovered dominating genotype as well as a creature having a purebred minority genotype for such specific characteristic.
It establishes whether the undiscovered genotype of the subject being examined is purebred allele dominant as well as heterozygous for something like the characteristic.

Thus the aforementioned response is correct.
