Evolution and conservation genetics

Evolution and conservation genetics. Neutral model of evolution. What governs heterogyzosity levels? Neutral model of drift and mutation Single population Constant size Drift occurs at rate 1/2N per generation Mutation creates new or alternative alleles and prevents fixation of alleles.

Evolution

Evolution. Definition: A process of change in species through time which is based on genetic variation. Example: Modern elephant is a result of a changes in ancestors over millions of years. Many ancestors have died but their DNA or genes are part of organisms that live today.
