Document Summary
Population genetic models: population genetic models: Pretty good at predicting if and how allele frequencies will change. As long as we are looking at only one or two loci: most traits, however, are determined by the combined influence of many proteins. Each coded by a different gene locus: quantitative genetics the branch of evolutionary biology that analyzes multilocus traits. Qualitative vs quantitative: introductory evolution and genetics deal with qualitative traits traits that exhibit only a few distinct categories flower color (red, white, or pink) Disease (have it or don"t have it) peapod shape (wrinkled or smooth: working with qualitative traits simplifies underlying mechanisms. Quantitative traits: quantitative traits are continuous require measurement, or quantification, to categorize. Height, speed, iq: quantitative traits are determined by. Combined influence of many different proteins coded from different dna regions (loci) Quantitative traits: the traits mendel studied were coincidentally (?) and fortunately qualitative.
