Across
- 8. group of individuals of the same species that live in the same area at the same time and can interbreed.
- 9. a necessary or desired commodity in an ecosystem- individuals of a population will compete for these.
- 11. type of natural selection in which individuals with the average phenotype have an advantage and the extremes are selected against.
- 13. the idea that those individuals best suited to their environment will achieve higher fitness.
- 14. migration of individuals out of population.
- 15. hardy-weinberg equations that states that all the dominant alleles(p)+ all the recessive alleles(q) represent all the alleles present in a population.
- 16. random changes in allele frequencies attributed to luck, not fitness.
- 18. isolation of a population due to differences in the time of mating.
- 19. when a small part of a population is separated from the rest and colonizes a new area they often respond differently to natural selection pressure.
- 20. when organisms will impersonate other organisms to increase fitness.
Down
- 1. isolation of a population due to differences in communication, mating rituals, or other behaviors.
- 2. selection within a population due to human interference and selection of desire traits.
- 3. migration of new individuals into a population.
- 4. isolation of a population due to physical barriers such as a fence, mountain range, or body of water.
- 5. describes the movement of genes/alleles/individuals between 2 neighboring population- makes population more alike.
- 6. collection of all the alleles present in a population.
- 7. measurement of the ability of an individual to survive and reproduce successful offspring.
- 10. percent of individuals of a population that have a particular trait- expressed as a number between 0 and 1.
- 12. ant characteristic that increases the fitness of and individual.
- 17. migration of new individuals into a population.
