Quantitative Inheritance
Quantitative inheritance, also called polygenic inheritance, describes traits controlled by multiple genes rather than a single locus. In cannabis breeding, most horticultural characteristics—plant height, flowering time, cannabinoid ratios, and terpene profiles—follow quantitative patterns. Each contributing gene typically adds a small, cumulative effect, producing continuous variation rather than discrete phenotypes. Breeders working in this category must track multiple generations and large population sizes to observe and select for desired trait combinations. Understanding quantitative inheritance is essential for developing stable cultivars with consistent agronomic and phytochemical profiles.

Quantitative traits require population-level selection strategies and longer breeding timelines than single-gene traits. Breeders use phenotypic selection, progeny testing, and sometimes marker-assisted breeding to identify individuals carrying favorable alleles across multiple loci, accelerating improvements in yield, potency, and environmental adaptation.
