Term
|
Definition
| Stabilizing selection that maintains a genetic disease in a population because heterozygotes resist an infectious disease |
|
|
Term
|
Definition
| Changes in the prevalence of a characteristic that reflects differential survival of individuals better adapted to a particular environment |
|
|
Term
|
Definition
| A population in which two extreme expressions of a trait are equally adaptive |
|
|
Term
|
Definition
| Genetic drift when small groups found new settlements, partition a subset of the original population's genes |
|
|
Term
|
Definition
| A change in a gene pool due to the random loss or addition of alleles through migration |
|
|
Term
|
Definition
| All the genes in a population |
|
|
Term
|
Definition
| Changes in gene frequencies caused by separation of a small group from a larger population |
|
|
Term
|
Definition
| Collection of deleterious alleles in a population |
|
|
Term
| Hardy-Weinberg Equilibrium |
|
Definition
| Maintenance of the proportion of genotypes in a population from one generation to the next |
|
|
Term
|
Definition
| A type of genetic drift. An event kills many members of a population, and a small number of individuals restore its numbers, restricting the gene pool |
|
|
Term
|
Definition
| When extreme phenotypes are less adaptive than an intermediate phenotype |
