Genetic Variance
Genetic variance in cannabis refers to the natural variation in terpene expression and cannabinoid profiles across individual plants within the same strain or cultivar. This phenotypic diversity arises from environmental factors, epigenetic expression, and the underlying genetic heterozygosity present in most cannabis populations. Understanding genetic variance is critical for breeders attempting to stabilize strains, as it explains why two plants from identical seeds can produce noticeably different terpene profiles. Lineage records frequently report that F1 hybrids and open-pollinated varieties display higher variance than inbred lines, making consistency a key breeding objective across multiple generations.

Breeders working to stabilize commercial strains must select for consistent terpene expression across generations, typically targeting F3-F7 to reduce variance. Conversely, breeders exploring new phenotypes deliberately preserve genetic variance in foundation stock to discover novel terpene combinations and plant structures.
