Natural Selection

4. the collection of all the alleles of all the genes in a population
6. a random change in allele frequencies in a population due to chance events
8. the change in allele frequencies in a population over time
11. a random change in the DNA sequence of a gene or chromosome
12. the proportion of a specific allele in a gene pool
13. the relative ability of an individual to survive and reproduce in its environment
14. the diversity of alleles and genotypes in a population

1. the process by which individuals with certain inherited traits have higher survival and reproduction than others in a given environment
2. a state in which allele and genotype frequencies in a population remain constant from generation to generation, assuming no evolutionary forces are acting
3. a group of individuals of the same species that live in the same area and interbreed
5. the evolution of new species or higher taxonomic groups from existing ones
7. the change in the heritable characteristics of biological populations over successive generations
9. the change in frequency of an allele due to its linkage with a beneficial allele on the same chromosome
10. a heritable trait that increases the fitness of an individual in a particular environment
14. the movement of alleles between populations due to migration or interbreeding
