Across
- 3. variation The differences among individuals in a population
- 4. type of natural selection in which individuals at either extreme of bell curve achieve higher fitness and the average is selected against
- 5. movement of individuals out of a population
- 10. collection of all the alleles present in a population
- 11. Movement of new individuals into a new population
- 14. percent of individuals that have a particular trait, expressed as a number between 0-1
- 15. drift random changes in allele frequencies to luck, not fitness
- 16. the idea that those individuals best suited to their enviornment will achieve higher fitness
- 17. due to physical barriers like fences and mountains
- 19. Hardy weinburg equation that states that all dominant alleles and all the recessive represent all the alleles in a population
- 20. state of genetic equilibrium characterized by a large population, no natural selection, random mating
- 21. any characteristics that increases the fitness of species
Down
- 1. individuals with the average phenotype have an advantage and the extremes are selected against
- 2. isolation due to differences in communication, mating rituals, etc
- 6. a necessary or destined commodity in an ecosystem-Individuals will compete for these
- 7. individuals with one extreme phenotype have an advantage and the other extreme is selected against
- 8. due to different times of mating
- 9. describes the movement of genes/individuals between two neighboring populations
- 12. measurement of the ability of an individual to survive and produce successful offspring
- 13. Hardy Weinberg equation that states that all the homozygous recessive individuals and all the heterozygous individuals and all the homozygous recessive alleles represent all individuals in a population
- 18. group of individuals of the same species in the same time and can interbreed
