Emily Jane McTavish published her DNA research in the Proceedings of the National Acedemy of Sciences.
Emily’s supporting data Working under the supervision of Alfred W. Roark Centennial Professor David Hillis, Ph.D., we funded two summer research fellowships for Emily Jane McTavish, Graduate student in Ecology Evolution Behavior, Section of Integrative Biology at the University of Texas at Austin, to analyze 50K chip data from Texas Longhorns and compare that to 50,000 alleles mapped from 57 other breeds of cattle in effort to identify breed-specific markers. Their research continued with a training grant to help discover the origins and admixture of the Texas Longhorn. Emily integrated data across platforms (Illumina 50K data with Bovine Genome Project HapMap data with USDA MARC data). She and Dr. Hillis collaborated with Jared E. Decker, Postdoctoral Fellow University of Missouri; Robert D. Schnabel, Research Assistant Professor-Division of Animal Sciences, University of Missouri; Jerry Taylor, Professor and Wurdack Chair of Animal Genomics, University of Missouri; Dr. Amparo Martínez Martínez, University of Córdoba, Spain, working in cooperation with SERGA, the Spanish Society for the Conservation of Animal Genetic Resources; and Mike Heaton, Ph.D. with the USDA Meat Animal Research Center also contributed data to the research project. Using the data analysis software STRUCTURE, Emily identified breed specific SNPs that place various breeds along a linear scale. She developed analysis software that interprets Illumina 6K chip data to calculate percent Indicus in individuals for comparison with populations to determine breed.
