Whole Genome Resequencing

What Is Whole Genome Resequencing?

Whole-genome resequencing is the genome sequencing of different individuals of species with known genome sequences, and based on this, individual or population differential analysis is performed. A large number of single nucleotide polymorphism (SNP) sites, insertion/deletion (InDel), structure variation (SV) sites and copy number variation (CNV) sites can be found by sequence alignment for whole genome resequenced individuals. Low-pass human whole-genome sequencing can also be performed to evaluate all types of genomic variants that replicate or delete larger lengths or entire chromosomes. Microbial whole genome sequencing can be used to identify and discover novel organisms or to identify specific bacterial organisms.

Deep genome-wide coverage of complex organisms requires technologies capable of high-throughput, cost-effective sequencing. Applications such as aneuploidy detection require lower depth of whole genome coverage and thus can take advantage of clear, accurate data generated by economically priced single-day workflows.
