Unit 6 Biology

2. Equation that states that all the dominatn alleles(p) and all the reccessive alleles(q) represent all the alleles in a populaion.
4. the idea that those individuals best suited to their environment will always achive higher fitness.
6. Isolation of a population due to differences in communication,mating rituals, or other behaviors
10. describes the movement of genes/alleles/individuals etween 2 neighbooring populations;makes population more alike
11. Type of natural selection in which individuals at either extreme of the bellcurve achieve higher fitness and the average is selected against.
14. when organisms will impersonate other organisms to increase fitness
15. Isolation of a population due to physical barriers
18. Type o natural selection in which individuals with one extreme phenotype have an agavantage and the other extrem is selcted against
20. Random changes in allele frequencies attributed to luck, not fitness

1. any characteristic that increases the fitness
3. Type of natural selection in which individuals with the average phenotype have the advantage and the extremes are selected agasinst.
5. percent of individuals of a population that have a particular trait; expressed as a number between 0 and 1
7. state of genetic euilibrium characterized by a large population, no migration,no natural selection, no mutations,and random mating
8. migration of a new indivdual into a populaton
9. Isolation of a population due to differences in timing of mating
12. selection within a population due to human intererence and selection of desired traits
13. Group of individuals of the same species that live in the same area at the same time and can interbreed.
16. measurment of the ability of an individual to survive and reproduc successful offspring
17. when a small part of a population is seperated rom the rest and colonizes in a new area; they often respond differently to natural selection
19. collection of all alleles present in a population
