Across
- 2. Measurement of the ability of an individual to survive and reproduce successful offspring
- 6. A necessary or desired commodity in an ecosystem - individuals of a population will compete for these
- 9. Describes the movement of genes/alleles/individuals between 2 neighboring populations - makes populations more alike
- 10. selection Type of natural selection in which individuals with one extreme phenotype have an advantage and the other extreme is selected against
- 13. isolation of a population due to differences in communication, mating rituals, or other behaviors
- 15. Collection of all the alleles present in a population
- 16. Type of natural selection in which individuals at either extreme of the bell curve achieve higher fitness and the average is selected against
- 18. When a population experiences a rapid, drastic reduction in the number of individuals in the population- reduces variation and changes allele frequencies of the population
- 20. idea that those individuals best suited to their environment will achieve higher fitness
- 21. Migration of new individuals into a population
- 22. Random changes in allele frequencies attributed to luck, not fitness Refers to the differences among individuals in a population
- 23. Percent of individuals of a population that have a particular trait - expressed as a number between 0 and 1
- 24. Hardy-weinberg equation that states that all the dominant alleles (p) + all the recessive alleles (q) represent all the alleles present in a population
Down
- 1. Selection within a population due to human interference and selection of desired traits
- 3. Isolation of a population due to physical barriers such as a fence, mountain range, or body of water
- 4. State of genetic equilibrium characterized by a large population, no migration, no natural selection, no mutations, and random mating
- 5. Group of individuals of the same species that live in the same area at the same time and can interbreed
- 7. 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
- 8. When organisms will impersonate other organisms to increase fitnes
- 11. Any characteristic that increases the fitness of an individual
- 12. Type of natural selection in which individuals with the average phenotype have an advantage and the extremes are selected against
- 14. Isolation of a population due to differences in the timing of mating
- 17. Hardy-weinberg equation that states that all the homozygous dominant individuals (p) + all the heterozygous individuals (2pq) + all the homozygous recessive individuals (q?) represent all the individuals in a population
- 19. Migration of individuals out of a population
