The Technology Tug-of-War: Microarray Genotyping vs. Next-Generation Sequencing in the Ancestry Testing Market
Description: A detailed comparison of the two leading technologies for analyzing DNA—Microarray SNP Genotyping and Next-Generation Sequencing (NGS)—and how their respective costs and data richness impact the market.
The technology underpinning the current Ancestry Testing Market is primarily Microarray SNP Genotyping. This method involves analyzing hundreds of thousands of pre-selected locations in the genome called Single Nucleotide Polymorphisms (SNPs). This technology is highly scalable and cost-effective; once a chip is designed, the cost of processing each individual test is low, which is the key reason companies like AncestryDNA and 23andMe have been able to offer kits at consumer-friendly prices. SNP data is highly effective for comparison and matching within their existing databases.
The emerging technology that represents the next phase of the Ancestry Testing Market is Next-Generation Sequencing (NGS), or whole-genome/whole-exome sequencing. NGS reads DNA much more broadly, providing a complete or near-complete…
