Color Genetics

Color genetics in cannabis refers to the heritable traits that determine pigmentation in leaves, bracts, and flowers. Anthocyanins, carotenoids, and chlorophyll interact with environmental conditions and genetic expression to produce phenotypes ranging from deep purples and blacks to bright oranges and reds. Breeders working in this category track color inheritance across generations to stabilize visually distinctive phenotypes. Color traits are often polygenic, meaning multiple genes contribute to the final expression. Documentation of color stability across photoperiod and temperature conditions helps establish breeding lines. Understanding the genetic basis of pigmentation supports both preservation of rare cultivars and development of new visual phenotypes.

Breeders select for consistent color expression to establish recognizable cultivar markers and meet market differentiation goals. Tracking color genetics across F1, F2, and backcross generations helps identify dominant and recessive pigmentation alleles, enabling predictable trait inheritance in future crosses.
