Bulk Segregant Analysis vs. Whole-Genome Shotgun Sequencing

What's the Difference?

Bulk segregant analysis (BSA) and whole-genome shotgun sequencing (WGS) are two different approaches used in genetic research. BSA is a method that involves the comparison of DNA from two or more groups of individuals with contrasting phenotypes to identify genetic markers associated with the trait of interest. It is a cost-effective and efficient way to identify genomic regions linked to a specific phenotype. On the other hand, WGS is a high-throughput sequencing technique that involves randomly fragmenting the entire genome and sequencing the fragments. It provides a comprehensive view of the entire genome, allowing for the identification of genetic variations and structural rearrangements. While BSA is focused on identifying specific genomic regions associated with a trait, WGS provides a broader understanding of the entire genome.
