Chromosomal Abnormalities
Chromosomal abnormalities in cannabis refer to structural or numerical variations in plant DNA that deviate from the typical diploid (2n) genome state. These variations—including polyploidy (triploidy, tetraploidy), aneuploidy, and chromosomal deletions or duplications—occur naturally in cannabis populations and have been documented in breeding records. While most plants with significant chromosomal aberrations exhibit reduced vigor or fertility, some polyploid specimens have been intentionally selected by breeders for altered morphology, terpene profiles, or cannabinoid expression. Understanding chromosomal status remains relevant to seed banking, breeding stability, and predicting offspring phenotypic consistency.

Breeders occasionally screen for polyploid lines to explore trait expression changes, though chromosomal instability typically reduces seed viability and plant reliability. Accurate karyotyping helps breeders identify stable genetic backgrounds and avoid propagating unstable germplasm.
