A Steak in Genomics™

The Beef Improvement Federation (BIF) will host a Genetic Prediction Workshop in Kansas City, MO on December 12-13, 2013 at the Holiday Inn KCI Airport and KCI Expo Center, 11728 NW Ambassador Drive.
The conference is designed to give academic, allied industry, breed association staff and cattle producers a forum to learn about and discuss the latest developments in beef cattle genetic evaluation strategies. The implementation of genomics technologies in national cattle evaluation systems will be the focus of discussion.  Speakers will highlight the experiences and current status of technology deployment at several major US breed associations, experiences developing genomic predictions of genetic merit and alternate strategies for computation of genomically enabled EPDs. The conference will also feature discussion of planned modifications to the system used to compute the Across Breed EPD adjustment factors at the US Meat Animal Research Center.

In addition to DNA variants' utility in predicting EPDs, disease risk, and other traits, they are also very useful in predicting an individual's ancestry. The most common use of this in livestock is parentage verification or testing. But DNA variants can also be used to look at relationships over much longer time scales. For example, my coauthors and I have used SNPs to look at relationships among ruminant speciesand breeds of cattle.


Last week I sent 10 mL of my saliva to 23andMe to for processing and DNA testing. This is the human equivalent of genomic-enhanced EPDs (although 23andMe uses different statistical methods). In addition to finding out if I carry specificgenetic disorders and my risk for common diseases, I will also find out about my ancestry.

One of the interesting things we have learned from sequencing ancient genomes is that most humans from Europe or Asia have Neanderthal ancestry. So, as part of my 23andMe results I will learn what percent of Neanderthal anc…
