Selective breeding and individual selection

What is "individual selection"? How can we use narrow-sense heritability to predict the outcome of a breeding programme? How can we use individual selection to estimate narrow-sense heritability? Why can't selection continue forever? What is the selection limit? What is a correlated response? This video lecture was recorded at the University of Wisconsin -- Stout in the fall of 2021. It accompanies my BIO 332 Genetics course, which was taught with Hartl's "Genetics: Analysis of Genes and Genomes."
