Tetraploid Expression
Tetraploid expression refers to cannabis plants with four sets of chromosomes rather than the typical diploid two sets. This chromosomal condition occurs naturally but rarely in cannabis populations, and breeders have selectively worked to stabilize tetraploid lines through controlled breeding. Tetraploid plants often exhibit larger flower structures, increased trichome density, and altered terpene profiles compared to diploid counterparts, though these traits vary by genetics. The polyploid condition can affect plant vigor, fertility, and cannabinoid expression, making tetraploid breeding a specialized pursuit within commercial genetics programs. Seed viability and fertility challenges are common obstacles in tetraploid line development.

Breeders exploring tetraploid expression primarily seek novel phenotypic variation and potential improvements in biomass and secondary metabolite production. Stabilizing fertile tetraploid lines requires careful selection and crosses, as chromosome doubling can disrupt normal meiosis and seed set.
