The FlySNP project
aims to provide the information and technical resources to support high-throughput positional cloning in Drosophila melanogaster
. These resources include a high-density genome-wide map of single nucleotide polymorphisms (SNPs), and inexpensive, high-throughput assays for SNP genotyping.
The specific aims were as follows:
1. To establish a map of >2200 SNP marker
loci in the Drosophila
These SNP markers have been identified in several commonly used genetic strains. The
FlySNP project identified SNP markers within the sequenced, euchromatic regions of
the X, 2nd and 3rd chromosomes. The average distance between SNPs is about
2. To establish robust, high-throughput assays
for SNP genotyping.
Assays have been established using PCR, microarray and mass-spectrometry methods. The tag-array mini-sequencing (TAMS) approach has proven to be an especially fast and reliable method for SNP genotyping.
