Evolutionary Concepts: Variation and Mutation

Prime objective of this lecture is to present on Evolutionary Concepts: Variation and Mutation. Here also briefly present on Microevolution: Changes within populations or species in gene frequencies and distributions of traits; and Macroevolution: Higher level changes, e.g. generation of new species or higher–level classification. Section of a chromosome that encodes the information to build a protein; Genetic information contained at a locus; Which alleles are actually present at a locus. Example: Alleles available: R and W. Possible genotypes: RR, RW, WW.
