Unit 6 Vocab

2. The idea that individuals best suited to their environment will achieve higher fitness.
3. Type of natural selection in which individuals with one extreme phenotype have an advantage and the other extreme is selected against
5. Random changes in allele frequencies attributed to luck, not fitness
7. Collection of all alleles present in a population.
14. Type of natural selection where individuals at either extreme of the bell curve achieve higher fitness and the average is selected against
18. The differences among individuals in a population
19. A necessary/desired commodity in an ecosystem
21. Selection within a population die to human interference and selection of desired traits
22. Isolation of a population due to differences in timing of mating

1. Isolation of a population due to physical barriers
4. Type of natural selection where individuals with the average phenotype have an advantage and extremes are selected against
6. When a population experiences a rapid/drastic reception in the number of individuals in the population; reduces variation and changes allele frequencies of the population
8. Characteristics that increase individual fitness
9. Describes the movement of genes/alleles/individuals between 2 neighboring populations; makes populations more alike
10. Percent of individuals of a population that have a particular trait; expressed as a number between 1-0
11. Group of individuals of the same species that live in the same area at the same time; can interbreed
12. When organisms will impersonate other organisms to increase fitness
13. Measurement of the ability of an individual to survive and reproduce successful offspring
15. When a small part of a population is separated from the rest and colonies a new area
16. Isolation of a population die to differences in communication, mating rituals, or other behaviors
17. Migration of new individuals into a population
20. Migration of individuals out of a population
