Across
- 1. isolation of a population due to physical barriers such as a fence, mountain range, or body of water
- 4. when a small part of a population is separated from the rest and colonizes a new area- they often respond differently to natural selection pressures
- 5. isolation of a population due to differences in the timing of mating
- 6. group of individuals of the same species that live in the same area at the same time and can interbreed
- 7. type of natural selection in which individuals with the average phenotype have an advantage and the extremes are selected against
- 11. random changes in allele frequencies attributed to luck not fitness
- 16. state of genetic equilibrium characteristic by a large population no migration no natural selection no mutations and random mating
- 17. percent of individuals of a population that have a particular trait- expressed as a number between 0 and 1
- 18. any characteristic that increases the fitness of an individual
- 19. when organisms will impersonate other organisms to increase fitness
- 20. collection of all the alleles present in a population
Down
- 2. migration of new individuals into a population
- 3. type of natural selection in which individuals with one extreme phenotype have an advantage and the other extreme is selected against
- 8. isolation of a population due to differences in communication mating rituals or other behaviors
- 9. describes the movement of general alleles individuals between 2 neighboring population makes population more alleles
- 10. type of natural selection in which individuals at either extreme of the ball curve achieve higher fitness and the average is selected against
- 12. measurement of the ability of an individual to survive an reproduce successful offspring
- 13. Hardy-Weinberg equations that states that all the dominant alleles put all the recessive alleles (q) represent all the alleles present in a population
- 14. the idea that those individuals best suited to their environment will achieve higher fitness
- 15. selection within a population due to human interference and selection of desired traits
