The troll doesn't understand polymorphism. No science, has he. He just regurges the Experts, and knows not what he speaks.
http://en.wikipedia.org/wiki/Polymorphism_(biology)
Polymorphism[1] in biology occurs when
two or more clearly different phenotypes exist in the same population of a species—in other words, the occurrence of more than one
form or
morph. In order to be classified as such, morphs must occupy the same habitat at the same time and belong to a
panmictic population (one with random mating).
[2]
Polymorphism as described here involves morphs of the
phenotype. The term is also used somewhat differently by molecular biologists to describe certain point mutations in the
genotype, such as
SNPs (see also
RFLPs). This usage is not discussed in this article.

Cannabis has dozens or even hundreds of Phenotypes in the base Species. As the crossbreeding bring us more strains, the strains are less stable for varied phenotype expressions, in some cases. Your Strain Hunters are making movies of themselves and are For Profit. And since you didn't quote a single thing we see it all as minor BS, trolling.

Sometimes you find a
cannabis strain so good, you can’t help but revisit the experience every time the opportunity presents itself. One day you might be surprised to discover a new batch of
Blue Dream looks nothing like the one you last tried: what was once a spear-shaped flower now looks like a chunky bulb of crystal trichomes. It’s the same strain, so what’s with the variability?
Two things influence the structural formation of any given cannabis plant: genetics and environment. The plant’s genetic makeup, also called a
genotype, acts as a blueprint for growth: it allows a spectrum of physical possibilities, but
it is up to the environment to induce these characteristics. The physical expression of a genotype is referred to as a
phenotype, which is simply defined as the traits that the environment pulls out from the plant’s genetic code. Everything from color, shape,
smell, and resin production are affected by the environment.
