1 To 1 Ratios

1:1 ratio genetics refer to cannabis cultivars bred to express roughly equal proportions of THC and CBD at harvest. These plants result from crossing high-THC lines with CBD-dominant parents, or selecting from populations that naturally stabilize cannabinoid expression. Breeders working in this category often pursue stable F2 or later generations to lock in consistent ratios across multiple plants. Lineage records frequently report crosses between modern CBD-rich cultivars and classic THC-forward strains. This trait has gained interest among breeders exploring diverse cannabinoid phenotypes beyond traditional high-THC breeding goals.

Breeders targeting 1:1 ratios typically employ test-cross strategies and cannabinoid profiling to identify parents likely to produce balanced offspring. Stabilizing this trait requires multiple generations of selection and often phenotype screening to achieve reliable plant-to-plant consistency.
