NextGen Logo

NextGen is a collaborative research project investigating the biodiversity of livestock species. NextGen used whole genome sequencing and genotyping microarrays to catalogue and study variation within populations of cattle, sheep and goat.

NextGen project genomic data sets are publicly available:

Variant Discovery
All SNPs and indels discovered from whole genome sequencing that passed the NextGen quality filters.
Genus level SNPs
Genotypes re-called at all known SNP sites within the genus. Intended for cross-species and cross-population comparisons.
Variant call sets were annotated with the Variant Effect Predictor.

1. [Seventy-five sheep from many different countries were were sequenced by the International Sheep Genomics Consortium (ISGC) and analysed by NextGen]

2. [Five Australian Capra hircus were sequenced by CSIRO and analysed by NextGen]

3. [Five Italian Capra hircus were sequenced by the project Genhome and were contributed to the Nextgen project by PTP and IBBA-CNR]
