Document Summary
Definition: changes in the genetic make-up of populations adaptation to the environment and the origin of new species. Definition: changes in the genetic make-up of . Polymorphism: ability to assume different forms or shapes. Ex: ladybug variation; black bug with 2 red spots or red bug with 2 black spots. Phenotypic variation due to genetics and/or environmental factors. Mutation: allele is changed such that it alters the genetic make-up of the gene. Lec 03: hardy-weinberg and the agents of evolution. Made up of individuals of same species, each with different genotypes. Incomplete dominance: individuals that are capable of showing traits of two different alleles. Use hardy-weinberg equilibrium to calculate if the population is evolving. Conclusion of experiment: the population of snapdragons are does not match the actual results. Disadvantageous mutations: harms an organisms: gene flow. Movement of alleles across different populations: genetic drift. Random change in allele frequencies: natural selection.
