Genetics - Facts, Information, and Encyclopedia Reference article (0 words) |
 | The word genetics was first applied to describe the study of inheritance and the science of variation by English scientist William Bateson in a letter to Adam Sedgewick, dated April 18, 1905. |
 | The foundational discipline is population genetics which studies the distribution of and change in allele frequencies of genes under the influence of the four evolutionary forces: natural selection, genetic drift, mutation and migration. |
 | While molecular genetics studies the structure and function of genes at a molecular level, ecological genetics focuses on wild populations of organisms, and attempts to collect data on the ecological aspects of individuals as well as molecular markers from those individuals. |

 | Genetic drift is the term used in population genetics to refer to the statistical drift over time of allele frequencies in a finite population due to random sampling effects in the formation of successive generations. |
 | Population genetics is the branch of biology that provides the mathematical structure for the study of the process of microevolution. |
 | Ecological genetics is the study of genetics (itself a field of biology) from an ecological perspective. |
