This course will familiarize students with fundamentals of genetic and their applications in animal breeding to improve livestock. Specifically understand: 1) basic genetics (chromosome structure, gene, cell cycle, gene mutation, Mendel?s laws, and classical genetic), 2) population genetics (genetic constituents of population, quantitative & qualitative traits, gene and genotypic frequencies, and Hardy-Weinberg equilibrium), and 3) selection & mating (how to select the best animal, selection for simply-inherited vs. polygenic traits, heritability & repeatability, and mating systems)
