Document Summary

Bio120: adaptation and biodiversity lab manual (chapter 2 . In association with lab 2 and lab quiz 1. Phenotypic variation can be due to environmental differences. Phenotypic plasticity is where a single genotype can produce different phenotypes in response to its environment. After reading, you should be able to: explain why phenotypic variation is important for evolution and adaptation, describe the factors that influence the expression of phenotypic traits, define phenotypic plasticity and explain how it relates to evolution. Identify the main components of, and be able to efficiently use, a compound and stereo microscope: use an ocular micrometer to calibrate a compound and stereo microscope, understand how to design an experiment to test a hypothesis. Phenotype is outward appearance or observable manifestation of a specific genotype. When darwin first assembled theory of evolution by natural selection, he implied a struggle for survival, so the winners are those whose phenotypes afford them the greatest fitness in a given environment.
