The Relation of Livestock Breeding to Theories of Evolution

The debt owed by quantitative geneticists to today's guest speaker is immeasurable. We quantitative geneticists are much concerned with the covariances among relatives, so I thought this introduction should include information on near relatives as well as individual performance data. For pedigree evaluation purposes, I thought it necessary to tell you a bit about Dr. Wright's father. Philip Green Wright was born in 1861, and took a Master's Degree at Harvard in Economics. Most of his academic career was spent at Lombard College in Gales-burg, IL. There he taught Economics, Mathematics, Astronomy and English, and was Director of the Gymnasium. He was a minor poet and would probably have to be judged unsuccessful in this endeavor, except that one of his student's, Carl Sandburg, enjoyed a bit of success. Another important relationship is that of full-sibs. Dr. Wright's two brothers were successful and able men. Quincy was a Professor of Political Science at the University of Chicago.
