BIOL 2081C Lecture Notes - Lecture 34: Quantitative Trait Locus, Selective Breeding, Inbreeding Depression
Document Summary
Many of the plants and animals used by humans for food, work, clothing, medicine, and other uses have been under artificial selection as part of domestication by humans for thousands of years. For example, grains like wheat and barley were domesticated around 10,000 years ago in. At about the same time, animals such as goats (mesopotamia) and chickens (asia) were some of the earliest domesticated animals. Today, we discuss artificial selection and its genotypic and phenotypic outcomes. Explain your answer: complete problem 2 on p 688 and analysis problem 18. 4 on p 689, go to, http://www. evo-ed. com/pages/peas/farming/farming. html and run the simulation for all three possibilities (no selection, selection for round, and selection for wrinkled). Broad-sense heritability: proportion of phenotypic variance that is caused by genotypic variance. i. e. the proportion of the phenotypic variance that is heritable. Phenotype variance: 2= 2+ 2, 2=22= 2, 2= .
