The fourth session of the Country Studies Webinar Series introduced DNA Fingerprinting as a powerful tool for improving the accuracy of variety identification in adoption studies. Davis Gimode explained key concepts—like genotype, phenotype, and fingerprinting—and highlighted the limitations of relying on farmer self-reports. With falling costs of genome-scale data, DNA fingerprinting is becoming a reliable and scalable method for adoption tracking. The session also walked through the full process: from building a reference library and collecting samples to genotyping and analysis.
