Snp Polymorphisms

SNP polymorphisms (Single Nucleotide Polymorphisms) are single-position variations in DNA sequences where different individual plants carry different nucleotides at the same genomic location. In cannabis breeding, SNP markers serve as molecular identifiers that distinguish genetic differences between plants and populations at a fine-grained level. These variations are inherited and stable across generations, making them valuable reference points for tracking lineage, verifying cultivar identity, and mapping trait associations. Breeders and researchers use SNP profiling to characterize genetic diversity within strain families, establish pedigrees, and understand population structure. SNP data has become increasingly accessible through genomic sequencing, enabling more precise documentation of cannabis genetics than visual or phenotypic observation alone.

Breeders employ SNP markers to verify seed authenticity, track parental contributions in hybrid crosses, and identify genetic relationships between cultivars. SNP polymorphisms also help researchers correlate specific genomic regions with observable traits, supporting informed selection strategies in breeding programs.
