Snp Markers

SNP markers (Single Nucleotide Polymorphisms) are single-base variations in DNA sequences used to identify genetic differences between cannabis plants. Breeders and geneticists use SNP markers as molecular tools to track inherited traits, verify plant parentage, and map disease resistance or cannabinoid production across populations. Unlike phenotypic observation alone, SNP analysis provides precise genetic fingerprinting at the DNA level. This classification reflects laboratory-based genetic screening rather than observable plant characteristics, making it valuable for seed banking, cultivar authentication, and breeding program management. SNP marker data helps standardize strain documentation across different growing regions and preservation protocols.

Breeders employ SNP markers to accelerate selection cycles by identifying carrier plants without waiting for trait expression, verify F1 hybrid vigor, and maintain genetic diversity records in long-term preservation programs. This molecular approach complements traditional phenotypic selection in structured breeding frameworks.
