Document Summary

Some examples will be discussed in class that are not in textbook. When you choose against aggression, you favour juvenile x. development; more than one trait is controlled by these genes; If you freeze maturation, it will change a wolf into a friendly puppy. 3. small variations may have large effects: hormones, developmental arrest, genetic variation & selection explains diversity of life. Add aa + vitamins; the wildtype version grew in both mediums; they thought they could mutagenize the fungus and grow it on minimal medium so find out which genes can"t grow in mm. Mm; this aa was arginine; it was added to the biosynthetic pathway and the fungus lived; i. find which nutrient rescues (complements) a given mutation. 1. infer mutation in a gene for the synthesis of that nutrient: e. g. find all mutants that grow on mm+arg, but not mm these are arg auxotrophs; defective in arg synthesis.
