Population Genetics

1. change in allele frequencies as a result of the migration of a small subgroup of a population.
6. type of speciation where a physical barrier separates a population.
7. formation of a new species.
9. groups of individuals of the same species that live in the same area.
10. movement of genes into or out of a population.
11. sum total of all the different forms of genetic information carried by a particular species, or by all organisms on earth.
12. type of speciation where a behavior separates individuals of the same population.

2. form of selection in which individuals at one end of a disruption curve have higher fitness than individuals in the middle or at the other end of the curve.
3. a change in the allele frequency following a dramatic reduction in the size of a population.
4. form of selection in which individuals at the upper and lower ends of the curve have a higher fitness than individuals near the middle of the curve.
5. all of the alleles that are present in a population at any one time.
6. number of times that an allele occurs in a gene pool compared with the number of alleles in that pool for the same gene.
8. type of selection in which individuals near the center of a disruption curve have a higher fitness than individuals at either end of the curve.
