|
2pq |
The frequency of heterozygous genotypes. |
Aa. The 2pq is part of the Hardy-Weinberg Model. |
|
|
q^2 |
The frequency of homozygous genotypes. |
aa. Also a part of the Hardy-Weinberg Model. |
|
|
Microevolution |
The changing of allele frequencies over many generations. |
Microevolution is caused by mutations. |
|
|
Natural Selection |
The picking of more common traits that will help the species survive in new environments. |
The natural selection of eyes depends on the intensity of light people live in. |
|
|
Gene Flow |
The transfer of genes when immigration occurs. |
Buffalo immigrating over long distances, mating with much more different organisms of the same species. |
|
|
Genetic Drift |
The change in frequency of alleles in organisms randomly. |
An allele taking over as more common because of a change in environment. |
|
|
Founder Effect |
Making a new population because of the loss of genetic variation. |
Darwin's birds traveling through the Galapagos Islands. |
|
|
Inbreeding |
The act of organisms breeding with close relatives. |
Endangered species breeding with themselves, eventually becoming homozygous. |
|
|
Population Bottleneck |
The big reduction in population of a species. |
Dodo birds becoming extinct. |
|
|
Inbreeding Depression |
The deterioration of skills in a species due to inbreeding. |
Horses mating with relatives, making offspring very weak. |
|
|
Quantitative Traits |
Traits produced because of supplements. |
Being born with more dopamine because of a supplement. |
|
|
Quantitative Trait Loci (QTLs) |
DNA eventually stretching and holding quantitative traits. |
Enlongation of something. |
|
|
Artificial Selection |
Breeding organisms until they produce traits that are wanted. |
Breeding dogs until a very strong one appears. |
