Uniparental Inheritance
Uniparental inheritance describes traits passed to offspring through only one parent rather than both. In cannabis, this occurs primarily through maternal (cytoplasmic) inheritance, where mitochondrial and chloroplast DNA transmit from the female plant to seeds. This contrasts with nuclear DNA inheritance, which follows Mendelian patterns from both parents. Uniparental traits include variegation patterns, chlorophyll deficiencies, and certain metabolic characteristics. Understanding these mechanisms is essential for breeders working with seed stability, crossing programs, and predicting offspring phenotypes across generations.

Breeders exploit uniparental inheritance to maintain specific maternal traits without segregation in F1 generations, particularly when working with stability in clone-only or seed-based lines. Recognizing which traits inherit uniparentally helps breeders avoid unexpected trait loss and design more predictable crossing strategies.
