In genetics, phenotype describes the observable characteristics of species. For Cannabis growers, phenotype refers to the physical expressions of the Cannabis plant. These expressions could be the plant’s height, color, resin production, shape, smell, and resistance to pests.
Phenotype is the result of the Cannabis growth’s genotype (genetic code) and the environmental factors. The genotype, or genetic makeup, serves as a growth blueprint: it provides for a range of physical possibilities, but it is up to the environmental conditions to bring about these features. Hybrid production among Cannabis plants is the perfect illustration of how genotype and environmental factors lead to desirable phenotypes.
