What are Marijuana Phenotypes and Genotypes?
When it comes to the world of cannabis cultivation, the right knowledge is very important. This will
be a very big determinant in the success of the cultivation process. This is why in this article, we
will be looking into two words that have commonly been misused and interchanged for each other
among many cannabis growers.
Phenotype and genotype are two common words used in the world of biology because they do a
great deal in explaining the makeup of every organism. They are also very important in the world
of cannabis cultivation as they provide a detailed insight into the intricate nature and makeup of
cannabis plants.
The need for the di erentiation between phenotypes and genotypes is because of the variations
and observations noted by cannabis growers in cannabis plants and it is very important that the
wrong notion isn't allowed to y around. The said observation is that cannabis plants that are
grown from the same seeds seem to have physical di erences which then begs the question of
whether the phenotype or genotype is the root cause of these di erences. The di erences range
from cannabis plant height, taste, smell, avor, and even e ects.
A closer look at Genotype and Phenotype
To fully understand the phenomenon, we will start by looking carefully into what genotype entails.
In simple terms, genotype refers to the genetic makeup or genetic information that characterizes
the traits that are observed in living organisms. The genetic information determines the
appearance, growth, scent, avor that can be seen in the cannabis plant. It is however necessary to
point out that the genotype of a cannabis plant doesn’t state with certainty the characteristics that
will be seen in the cannabis plant, instead it o ers a range of possibilities.
A very important determinant in the form with which the information coded in the genetics of a
cannabis plant expresses itself is the environment. We cannot talk about the genotype of a
cannabis plant and the role it plays with the nal results seen in the cannabis plant without talking
about the environment. The factors of the environment play a huge role in determining which of

the parts of the genotype get to be activated and expressed in the cannabis plant. As said earlier,
the genotype doesn’t determine what nally gets expressed, it only contains a range of possible
traits that can be expressed. It is the interactions with the environment that accounts for the
characters to be seen.
The nal product of the genetic information and the environment and the interaction between the
genotype and the environment is what is called the phenotype. The phenotype is the physical
result after the di erent factors in the environment trigger and activates some of the genetic
information embedded in the genetic makeup of the cannabis plants. For every cannabis grower,
the importance of the di erent factors and conditions that must be maintained in the growing
area are well known as these play a huge role in the success of the cultivation process. These
factors too are to be thanked to a large extent for the uniqueness that is seen among some plants
of the same strain.
The e ect of this can be seen when you consider seeds from the same cannabis strain being
grown indoors and outdoors. The e ects of the temperature, light, humidity, and other factors will
play a very huge role in the physical characteristics of the plant as the outdoor plants can be seen
to have plants with richer purple colors in comparison to the cannabis plants that are grown
indoors.
Why do plants grown in the same environment have di erences?
Now the explanation regarding the phenotype and genotype gives a good basis for the reason why
seeds from the same cannabis plants can express themselves di erently based on the
environment they are exposed to. There still remains another observation that is very common
among di erent cannabis growers which is that seeds of cannabis plants that are grown under the
same conditions can also have di erent phenotypes. This observation begs the question as to
what else plays a role in in uencing the physical outcome of the cannabis plant.
The common misassumption that occurs here is that many believe the reason for these variations
in cannabis plants that are grown under the same conditions is because of their phenotype. This is
why it was necessary for us to rst establish that the environment expresses the phenotype from
the genotype and not the other way around. The question however still remains as to what the
root cause of this di erence is and the answer lies in the genotype.
Many cannabis growers expect that the genotype of the seeds of cannabis plants should be
identical since they come from the same origin. The truth however is that this has always been a
huge misassumption. Unlike the expectation that the genotypes are identical, they are actually
similar but still contain di erences between them. And a simple way to express this is through
identical twins. Contrary to the expectation that the genetic information should express
themselves completely alike, they are actually like siblings.
This explains the uniqueness and variations that are seen in cannabis seeds from the same origin
grown under the same environmental conditions. This in uences the taste, smell, odor, and shape
of the cannabis plant as individual seeds have individual genetic codes.

Hybrids and Clones
The knowledge of the di erences between phenotype and genotype is also important when it
comes to the making of hybrids and the expected results. Hybrids are bred for their ability to join
the bene cial characteristics of indica strains and sativa strains and the knowledge of this
relationship will be important when plants have dominant sativa genetic yet still show more indica
characteristics.
If the goal is to have the same cannabis plants with identical characteristics, clones are the way to
go. The genotype of the young plant will be the same as that of the mother plant and when grown
in the same environment, they will express with the same types of physical characteristics.

What is Guerilla Cannabis Growing and How Do You Do It?
This method of cannabis cultivation involves the grower cultivating the cannabis plant in an open outdoor location with the hope
that the plant won't be accidentally discovered by others. Asides the obvious bene t of privacy, Guerrilla growing also allows the
plant to grow wild and get exposed to the elements which fosters a more natural growth that can be controlled with occasional…
