Inbreeding depression: Inbreeding depression is the reduced biological fitness in a given population as a result of inbreeding, or breeding of related individuals. Population biological fitness refers to its ability to survive and reproduce itself.Genetic load: Genetic load is the difference between the fitness of the theoretically optimal genotype and the fitness of the observed average genotype in a population. This means that populations with a low genetic load will tend to be healthier, have fitness that is less dispersed, and have offspring that are more likely to survive to reproduction.Panmixia: Panmixia (or panmixis) means random mating.King C and Stanfield W.Cousin couple: A cousin couple is a pair of cousins who are involved in a romantic or sexual relationship.Reproductive toxicity: Reproductive toxicity is a hazard associated with some chemical substances, that they will interfere in some way with normal reproduction; such substances are called reprotoxic. It includes adverse effects on sexual function and fertility in adult males and females, as well as developmental toxicity in the offspring.Genetic variation: right|thumbPlant breedingF1 hybrid: An F1 hybrid (or filial 1 hybrid) is the first filial generation of offspring of distinctly different parental types. F1 hybrids are used in genetics, and in selective breeding, where it may appear as F1 crossbreed.Terminal crossbreeding: Terminal crossbreeding is a breeding system used in animal production. It involves two (different) breeds of animal that have been crossbred.Selection (relational algebra): In relational algebra, a selection (sometimes called a restriction to avoid confusion with SQL's use of SELECT) is a unary operation written asMicrosatellite: A microsatellite is a tract of repetitive DNA in which certain DNA motifs (ranging in length from 2–5 base pairs) are repeated, typically 5-50 times. Microsatellites occur at thousands of locations in the human genome and they are notable for their high mutation rate and high diversity in the population.Sexual motivation and hormones: Sexual motivation is influenced by hormones such as testosterone, estrogen, progesterone, oxytocin, and vasopressin. In most mammalian species, sex hormones control the ability to engage in sexual behaviours.Antelope: An antelope is a member of a number of even-toed ungulate species indigenous to various regions in Africa and Eurasia. Antelopes comprise a wastebasket taxon (miscellaneous group) within the family Bovidae, encompassing those Old World species that are not cattle, sheep, buffalo, bison, or goats.Threshold host density: Threshold host density (NT), in the context of wildlife disease ecology, refers to the concentration of a population of a particular organism as it relates to disease. Specifically, the threshold host density (NT) of a species refers to the minimum concentration of individuals necessary to sustain a given disease within a population.Biological ornament: A biological ornament is a secondary sexual characteristic of an animal that appears to serve a decorative function rather than an ostensible, utilitarian function. Ornaments are used in displays to attract mates in a process known as sexual selection.Pedigree chart: A pedigree chart is a diagram that shows the occurrence and appearance or phenotypes of a particular gene or organism and its ancestors from one generation to the next,pedigree chart Genealogy Glossary - About.com, a part of The New York Times Company.Solanum chacoense: Solanum chacoense is a species of wild potato. It is native to South America, where it can be found in Brazil, Bolivia, Argentina, Peru, Uruguay, and Paraguay.PollenMatrix population models: Population models are used in population ecology to model the dynamics of wildlife or human populations. Matrix population models are a specific type of population model that uses matrix algebra.CarallumaLow Fertility Cohorts Study: The Low Fertility Cohorts Study, 1978: A Survey of White, Ever-Married Women Belonging to the 1901-1910 United States Birth Cohorts,Data Sharing For Demographic Research consists of personal interviews of white, ever-married women born between July 1, 1900, and June 30, 1910. In 1978, a national survey of 1,049 married women between the ages of 68 and 78 were interviewed between the months of March and July in order to investigate low fertility during the 1920s and 1930s and the women of childbearing age during those decades.Victor Willard: Victor M. Willard (1813 – December 10, 1869) was an American farmer from Waterford, Wisconsin who spent two years (1849–1850) as a Free Soil Party member of the Wisconsin State Senate from the 17th District.Dipsacus: Dipsacus is a genus of flowering plant in the family Caprifoliaceae. The members of this genus are known as teasel, teazel or teazle.Infinite alleles model: The infinite alleles model is a mathematical model for calculating genetic mutations. The Japanese geneticist Motoo Kimura and American geneticist James F.Santa Fe College Teaching ZooRobinia hispida: Robinia hispida, known as the bristly locust, rose-acacia, or moss locust, is a shrub in the subfamily Faboideae of the pea family Fabaceae. It is native to the southeastern United States,Robinia hispida.Microevolution: Microevolution is the change in allele frequencies that occur over time within a population.Microevolution: What is microevolution?Silene undulataEvolution in Variable EnvironmentMeramec Conservation AreaTomato seed oil: Tomato seed oil is a vegetable oil extracted from the seeds of tomatoes.Ippolito de' MediciInterbreeding of dingoes with other domestic dogs: The interbreeding of dingoes with other domestic dogs is an ongoing process affecting the population of free ranging domestic dogs in Australia. The current population of free ranging domestic dogs in Australia is now probably higher than in the past.Lychnis flos-cuculi: Lychnis flos-cuculi, commonly called Ragged-Robin, is a herbaceous perennial plant in the family Caryophyllaceae. It is species is native to Europe, where it is found along roads and in wet meadows and pastures.Flower box: __NOTOC__Deep litter: Deep litter is an animal housing system, based on the repeated spreading of straw or sawdust material in indoor booths. An initial layer of litter is spread for the animals to use for bedding material and to defecate in, and as the litter is soiled, new layers of litter are continuously added by the farmer.AmborellaTriodanis perfoliata: Triodanis perfoliata, the Clasping Venus's Looking Glass, is a flowering plant belonging to the family Campanulaceae. It is an annual herb native to North and South America, the natural range extending from Canada to Argentina.List of Acacia species used for tannin production: This is a list of Acacia species (sensu lato) that are used for the production of tannins.Health geography: Health geography is the application of geographical information, perspectives, and methods to the study of health, disease, and health care.CoproliteBoraginoideae: Boraginoideae is a subfamily of the flowering plant family Boraginaceae, as that family is defined in the APG III system of classification for flowering plants. The Angiosperm Phylogeny Group has not actually specified subfamilies within Boraginaceae.Amelanchier alnifolia: Amelanchier alnifolia, the saskatoon, Pacific serviceberry, western serviceberry, alder-leaf shadbush, dwarf shadbush, chuckley pear, or western juneberry,Germplasm Resources Information Network: Amelanchier alnifolia is a shrub with edible berry-like fruit, native to North America from Alaska across most of western Canada and in the western and north-central United States. Historically, it was also called pigeon berry.
