Researchers announced today that they have successfully resequenced the DNA of 15 mouse strains most commonly used in biomedical research. More than 8.3 million single nucleotide polymorphisms (SNPs) were discovered among the genomes of the 15 mouse strains and the data are now publicly available. These new data will help researchers better understand complex genetic traits, such as why some individuals are more susceptible to certain diseases, and will serve as a valuable resource in determining how environmental agents influence the development of disease. >>> Discuss This Story
