In 2008, a dna technology company, florigene, ltd., a japanese subsidiary from australia, claimed the production of a genetically blue rose. this was a great success since roses have no natural gene for producing blue pigments; further, roses do have a gene that controls the destruction of blue pigment molecules. to obtain the blue color, researchers had to inject genes from pansies and other flowers to counteract the natural chemistry of the plant. the blue flower that florigene produced is an example of

Transgenic organism.

Explanation:

Transgenic organism can be produced by altering the genome of the organism by molecular techniques. The genes can be modified or the new genes can be introduced in the organism.

The scientists has created the blue color rose by altering the genome of red flower and introduced the blue pigment in the flower. The blue color flower has florigene that acts as the transgenic organism as its gene has been modified.

Thus, the correct answer is transgenic organism.

the denominator has a very specific role.

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.
