About Variants

iDog houses the variation information of dog/wolf genomes. It was designed and constructed as a SNPs detector and visualization tool to provide the research community a useful resource for the study of dog's population, evolution, phenotype and life habit. In the current version, DogSD contains 71 millions non-redundant SNPs called from 722 individual samples and 6 millions ancient SNPs called from 27 individual samples.
