Dominant And Recessive Traits

Dominant and recessive traits form the genetic foundation of cannabis inheritance, following Mendelian inheritance patterns observed across plant breeding programs. A dominant trait expresses visibly when inherited from one parent (heterozygous), while recessive traits require matching alleles from both parents (homozygous) to manifest phenotypically. In cannabis, traits like leaf morphology, flowering time, and pigmentation demonstrate these patterns, though many horticultural characteristics involve multiple genes. Breeders track dominant versus recessive expressions to predict offspring phenotypes and stabilize desired characteristics across generations. Understanding this framework is essential for anyone studying cannabis genetics, selective breeding methodology, or strain development documentation.

Breeders leverage dominant/recessive understanding to stabilize lines (fixing homozygous traits), plan crosses predictably, and identify carrier plants for hidden recessive genetics. This knowledge accelerates breeding programs by clarifying which traits will breed true and which require further selection.
