What is Genotyping by Sequencing?

Genotyping by sequencing (GBS) is a powerful, cost-effective technique that enables genome-wide analysis without requiring a reference genome. Perfect for researchers working with non-model organisms or those just starting their genomic research journey.

🧬

No Reference Genome Needed

GBS works beautifully with novel species, making it accessible for researchers without prior genomic resources.

đź’°

Cost-Effective

Dramatically reduce sequencing costs compared to traditional methods while maintaining high data quality.

đź“Š

High-Throughput

Analyze hundreds to thousands of samples simultaneously, accelerating your research timeline significantly.

🔍

Versatile Applications

From population genetics to breeding programs, GBS adapts to diverse research needs and scientific questions.

How It Works

Step 1: Sample Preparation

It all starts with high quality DNA extractions, with rigorous QC to ensure optimal results from the start.

Step 2: Reduced Representation Library

Restriction enzyme digestion creates a consistent, reproducible subset of the genome for targeted sequencing.

Step 3: Library Sequencing

Pool and sequence libraries on next-generation platforms, generating vast amounts of sequence data efficiently.

Step 4: Bioinformatics Analysis

Specialized pipelines identify SNPs, calculate genetic distances, and generate population-level insights.

Why Choose GBS?

  • Scalability: From pilot studies with a few samples to large-scale population analyses
  • Reproducibility: Consistent results across laboratories and runs
  • Compatibility: Works with various DNA extraction methods and sample types
  • Proven Track Record: Citations in thousands of publications across research applications

What Can You Do With GBS?

Population Genetics

Estimate genetic diversity, population structure, and gene flow across species. Study evolutionary processes and conservation genetics.

Breeding Programs

Identify trait-associated markers, implement genomic selection, and accelerate breeding progress in plants and animals.

Taxonomy & Phylogenetics

Delve into species boundaries, phylogenetic relationships, and systematics with genome-scale marker data.

Disease Resistance Studies

Map resistance loci, quantify genetic variation for disease tolerance, and develop resistant cultivars or breeds.

Parentage & Kinship Analysis

Determine parentage, assign individuals to populations, and estimate relatedness with high accuracy.

Ecological Genomics

Connect genotype to phenotype in natural environments. Study local adaptation and ecological traits at the genomic scale.
