Plant Genetics

Plant genetics refers to the inherited traits and DNA sequences that determine cannabis phenotype expression, cannabinoid ratios, terpene profiles, and structural characteristics. Breeders study plant genetics to understand how traits pass between parent plants and how environmental factors interact with genotype to produce observable characteristics. Understanding plant genetics is foundational to cannabis breeding programs, seed stability, and the reproducibility of desired traits across generations. Lineage records, backcrossing programs, and controlled pollination all depend on knowledge of how genetic information is transmitted and expressed. Plant genetics encompasses both nuclear DNA and maternal inheritance patterns, which influence everything from leaf morphology to resin production.

Breeders use plant genetics principles to select parent plants with desired traits, create stable F1 hybrids, and develop true-breeding lines through controlled crosses and selection pressure. Understanding dominance patterns, gene linkage, and epistasis helps breeders predict offspring phenotypes and avoid undesired trait combinations.
