Genotype Testing

Genotype testing refers to the molecular identification and analysis of cannabis plant genetics, used by breeders and seed producers to verify lineage, detect genetic markers, and confirm seed authenticity. Modern genotype testing employs DNA sequencing and microsatellite analysis to map genetic profiles across plant populations, helping distinguish between phenotypically similar cultivars and establish reproducible strain identities. Testing protocols vary widely across jurisdictions and breeding operations, from simple parentage verification to comprehensive genomic mapping. This practice has become increasingly standard in regulated seed markets and professional breeding programs seeking to document genetic stability, detect unwanted contamination, and maintain breeding records. Genotype data also supports conservation efforts for heritage genetics and enables breeders to make informe

Breeders use genotype testing to confirm heterozygosity levels in F1 crosses, verify parental purity before breeding programs, and identify recessive traits that may not express in the phenotype. Detailed genetic profiles allow breeders to select for specific alleles linked to desired traits and avoid genetic drift across seed generations.
