Chromosome Mapping
Chromosome mapping in cannabis refers to the systematic identification and cataloging of genetic markers along the plant's chromosomes. This foundational genomics work helps breeders understand the physical location of genes responsible for traits like cannabinoid production, flowering time, and disease resistance. Cannabis has ten chromosome pairs, and mapping projects document which regions correlate with observable traits (phenotypes). Modern mapping uses molecular markers—short DNA sequences that vary between plants—to track inheritance patterns across generations. This data supports more precise breeding decisions and helps researchers distinguish between genetic variation and environmental influence on plant development.
Chromosome Mapping strains
No strains tagged into Chromosome Mapping yet — they'll appear here as breeders submit lineage records under this family.

Breeders leverage chromosome maps to accelerate selection for specific traits without waiting for multiple generations of field trials. Mapped markers enable marker-assisted selection (MAS), allowing breeders to identify desirable genetics in seedlings before flowering or full maturation.
