Document Summary
Describe characteristics of a population that is in the hardy-weinberg equilibrium. Outline the di erences between allele frequency and genotype frequency. Demonstrate how success of di erent phenotypes can be compared by calculating their relative tness. Explain what is meant by genetic drift. Describe the phenomena of bottleneck e ect and founder e ect and explain how they contribute to changes in allelic frequencies. Describe how migration and nonrandom mating patterns a ect genetic variation in population. Study of genes and genotypes in a population. How it changes over the course of many generations. Helps us understand how genetic variation is related to the phenotypic variations. Genotype: set of allele that determines (in part) the expression of a particular trait. Phenotype: physical (or biochemical) expression of a trait based on genes and environment. All of the alleles for every gene in a given population.
