F IT is the inbreeding coefficient of an individual (I) relative to the total (T) population, as above; F IS is the inbreeding coefficient of an individual (I) relative to the subpopulation (S), using the above for subpopulations and averaging them; and F ST is the effect of subpopulations (S) compared to the total population (T), and is ...
In the absence of mutation or heterozygote advantage, any allele must eventually either be lost completely from the population, or fixed, i.e. permanently established at 100% frequency in the population. [2] Whether a gene will ultimately be lost or fixed is dependent on selection coefficients and chance fluctuations in allelic proportions. [3]
When considering more disaggregated data for 26 European populations, the smallest genetic distance (0.0009) is between the Dutch and the Danes, and the largest (0.0667) is between the Lapps and the Sardinians. The mean genetic distance among the 861 available pairings of the 42 selected populations was found to be 0.1338. [page needed].
In statistics, a population is a set of similar items or events which is of interest for some question or experiment. [1] [2] A statistical population can be a group of existing objects (e.g. the set of all stars within the Milky Way galaxy) or a hypothetical and potentially infinite group of objects conceived as a generalization from experience (e.g. the set of all possible hands in a game of ...
A position that is deemed the most important to a given individual is called central, others are peripheral. If a sequence of positions is required to obtain a given position, it can be defined as a career, and a change of position in this context is a promotion or demotion. Some social positions may make it easier for a given person to obtain ...
In probability theory, a probability density function (PDF), density function, or density of an absolutely continuous random variable, is a function whose value at any given sample (or point) in the sample space (the set of possible values taken by the random variable) can be interpreted as providing a relative likelihood that the value of the ...
In high throughput sequencing, data obtained are typically transformed to relative abundances, rendering them compositional. In probability and statistics , a partition of the sampling space into disjoint events is described by the probabilities assigned to such events.
Ascribed status is an arbitrary system of classifying individuals that is not fixed in the way that most people think. Status is a social phenomenon rather than a biological one. The meaning is derived from the collection of expectations of how an individual should behave and what the expected treatment of that individual is.
