Welcome to the SNPduoWeb website. This tool is designed to provide an analysis of Single Nucleotide Polymorphism (SNP) data between any two individuals. It has been designed based on data exported from Affymetrix CNAT 4.0 or Illumina Beadstudio, as well as data downloaded from the HapMap project. However, provided that the data is formatted correctly SNPduoWeb can analyze any SNP data.
