Will Shaffer

Graduate Research Assistant
Hometown: Carthage, MO

B.S., Oklahoma State University, 2017
M.S., Kansas State University, 2021
Ph.D., Genetics
Graduate Certificates: Applied Statisticsin, 2021

Project Description: My Masters focused on modeling and selecting for phenotypic stability and the impacts of genetic-by-environment interactions on selection. My Ph.D. involves emerging technologies in genetic evaluation. Some of my projects include miRNA differential expression analysis, developing a sire conception rate genetic evaluation for beef sires used in dairy populations, and modeling genetic variance and performance across the landscape of the United States.

Jasmine Morey

Graduate Research Assistant
Hometown: Hiawatha, KS
B.S. Animal Sciences and Industry
M.S. Genetics and Breeding
Menzi Spiller Benton
Graduate Research Assistant
Hometown: Fredericksburg, TX
B.S., Animal Science, Texas A&M University, 2020
M.S. Project Description: Heritability of heart failure in feedlot cattle
We plan to analyze phenotypic traits, pedigrees, and full genomes collected on cattle in a feedlot at a moderate altitude that developed heart failure during the feeding period. This is in an effort to determine heritability estimates for heart failure and possibly the genetic distinction between heart failure that develops at high altitudes versus feedlot heart failure.
