BoardGameGeek was founded in January 2000 by Scott Alden and Derk Solko, [6] and marked its 20th anniversary on 20 January 2020. [7]Since 2005, BoardGameGeek hosts an annual board game convention, BGG.CON, that has a focus on playing games, and where winners of the Golden Geek Awards are announced.
Hamlet or Band – a hamlet has a tiny population (fewer than 100), with only a few buildings. A social band are the simplest level of foraging societies with generally a maximum size of 30 to 50 people; consisting of a small kin group, no larger than an extended family or clan.
The number of possible person-to-person links (L) increases rapidly as the size of the group (N) increases (L = (N² - N) /2). In a four-member group there are six possible pairings; add a fifth member for each of the four to relate to and you have ten pairs. The number of possible two-person links in a group of twelve is 66.
Also, actual genetic findings may be overlooked if the locus is less prevalent in the population where the case subjects are chosen. For this reason, it was common in the 1990s to use family-based data where the effect of population structure can easily be controlled for using methods such as the transmission disequilibrium test (TDT). [28]
In the absence of population structure, Hardy-Weinberg proportions are reached within 1–2 generations of random mating. More typically, there is an excess of homozygotes, indicative of population structure. The extent of this excess can be quantified as the inbreeding coefficient, F. Individuals can be clustered into K subpopulations.
Population structure may refer to many aspectsof population ecology: Population structure (genetics) , also called population stratification Population pyramid

In population genetics, the Watterson estimator is a method for describing the genetic diversity in a population. It was developed by Margaret Wu and G. A. Watterson in the 1970s. [1] [2] It is estimated by counting the number of polymorphic sites. It is a measure of the "population mutation rate" (the product of the effective population size ...
