Array-Based Genomic Diversity Measures Portray Mus Musculus Phylogenetic And Genealogical Relationships, And Detect Genetic Variation Among C57bl/6j Mice And Between Tissues Of The Same Mouse, Susan T. Eitutis

Electronic Thesis and Dissertation Repository

Mouse models lack affordable genomic technologies slowing the identification of candidate variants contributing to complex phenotypes. The Mouse Diversity Genotyping Array (MDGA) is a low cost, high-resolution platform permitting genomic diversity assessment. Using a validated list of >500,000 single nucleotide polymorphisms (SNPs), we applied the first comprehensive analysis of SNP differences to detect genetic distance across 362 Mus musculus samples. Genetic distance measured between distantly and closely related mice correlates with known phylogeny and genealogy. Variation detected between C57BL/6J mice is consistent with previous reports of variants within this strain. Putative genetic variation detected between and within tissues indicates somatic …
