Document Summary
Identical twins have same genetic makeup: even slight differences in environment lead to variation in behaviours, phenotypes reflect both genetic and environmental effects. Z = g+ e (phenotype= genes + environment: within population- variation in behaviour. Rover-sitter polymorphism: rover: travels far distances as a larva. -what happens when they cross: results: f2 generation 3:1 ratio - means that one gene, two alleles and rovers are dominant, what do these foraging alleles produce, pkg: One genotype will respond completely differently to the other genotype: evolution of reaction norms. 13-02-11 9:18 pm: how different are the sexes and why, two phenotypes, sexually dimorphism quite apparent is many species. Weigh (+) mating success with (-) survival (predation: sexual selection, don"t think about it as a sense of beauty, sexually selected traits function to enhance mating success. I. e. frigget birds don"t think, gee that"s attractive Subset of natural selection: sexual selection:
