| genetic change in a species over time |
|
|
Term
|
Definition
| small-scale changes in allele frequencies brought about by mutation, natural selection, gene flow, and genetic drift |
|
|
Term
|
Definition
| all the genes in the population |
|
|
Term
|
Definition
| has severe effects on phenotype and usually results in death |
|
|
Term
|
Definition
| a mutation that doesn't help or harm the individual |
|
|
Term
|
Definition
Introduces or removes alleles from a population by emigration of immigration
Ex: Blue people of KY |
|
|
Term
|
Definition
| a random increase or decrease of alleles that are most apparent in a small population |
|
|
Term
|
Definition
Founder effect
Bottleneck |
|
|
Term
|
Definition
- Type of genetic drift
- allele frequencies in a group of migrating individuals are by chance no the same as that of their population of origin
- Ex: amish and polydactylism
|
|
|
Term
|
Definition
- Type of genetic drift
- population undergoes a dramatic decrease insize due to a catastrophy
|
|
|
Term
|
Definition
| the frequencies of alleles remain constant from generation to generation. population is not evolving |
|
|
Term
| 5 conditions of genetic equilibrium or Hardy Weinberg |
|
Definition
- no mutations
- population is very large
- population is isolated (no gene flow)
- no selection pressure (no genotype has an advantage over another)
- random mating
