genealogy The study of the history of families and the line of descent from their ancestors.
Genetics The branch of biology that deals with heredity and genetic variations. The genetic makeup of an organism or group of organisms.
Genetic Drift The change in the relative frequency in which a gene variant [allele] occurs in a population due to random sampling and chance: The alleles in offspring are a random sample of those in the parents, and chance has a role in determining whether a given individual survives and reproduces. A population's allele frequency is the fraction of the gene copies that share a particular form. Genetic drift is an important evolutionary process, which leads to changes in allele frequencies over time. It may cause gene variants to disappear completely, and thereby reduce genetic variability. In contrast to natural selection, which makes gene variants more common or less common depending on their reproductive success, the changes due to genetic drift are not driven by environmental or adaptive pressures, and may be beneficial, neutral, or detrimental to reproductive success. The effect of genetic drift is larger in small populations, and smaller in large populations.
genus A category in the taxonomic classification of related organisms, comprising one or more species. Similar genera are grouped into families.
geocentric Relating to imagery that thematically consists primarilv of nonfigurative, abstract-geometric configurations.
geoglyph A ground figure created by scraping away the patinated surface material of desert pavement to expose the underlying lighter colored soil; also known as intaglio. For example, the ancient Nasca lines of Peru.
