Snp Analysis

SNP analysis (Single Nucleotide Polymorphism analysis) refers to the genetic sequencing and identification of single-base variations in cannabis DNA. These point mutations—where one nucleotide differs from a reference sequence—serve as molecular markers for lineage verification, genetic diversity assessment, and breeding program tracking. SNP profiling enables breeders and researchers to map genetic distances between cultivars, confirm parentage claims, and detect genetic contamination or drift in seed stocks. Unlike phenotypic observation alone, SNP data provides objective, reproducible evidence of genetic relationships across cannabis germplasm. This technique has become increasingly accessible as sequencing costs decline, allowing larger breeding operations and research institutions to employ genomic tools alongside traditional selection methods.

Breeders use SNP analysis to validate claimed lineages, identify genetically distinct parents for hybridization programs, and monitor genetic purity across generations. SNP markers also help characterize rare alleles or trait-linked variants in closed populations.
