Unformatted text preview: Genetic Investigation { traits chromosomes DNA Reverse genetics : start with the DNA, then use model organisms to test how changing the DNA affects traits. The genomes of humans and chimpanzees differ by only a small percentage of nucleotides Model Organisms What traits are useful? • ability to grow large numbers of individuals • fast generation time • ease of growing in laboratory • simple genetics • applicability to problems of interest • knowledge and reagents available Most commonly studied model organisms: • viruses • E. coli • yeast • Neurospora (filamentous fungi) • Arabidopsis thaliana • Caenorhabditus elegans • Drosophila melanogaster • frog • zebrafish • mouse • human (cell culture) Model Organisms...
