Also, Ireland is severely lacking in diversity of haplotypes, probably as they are most closely related to an Ice Age refuge population from which Europe was partially repopulated, [albeit with small contributions from Iberia and Western France in the Neolithic and Bronze Age]. @Amber Hi, I was very interested in the comments about the Dutch.

Relationship between F and demographic rates: W inbred = W out x e (-B F) where W = survival (S x) or fecundity (m x) F = the inbreeding coefficient B = the number of lethal equivalents per gamete "B" is a measure of the rate at which survival or fecundity decreases with increased inbreeding. See a recent comment of mine over at HBD Chicks.

If you want to compare this sort of stuff,use pre-USSR maps. Afrikaner genomics. Genetic bottlenecks and inbreeding can increase the frequency of deleterious variants, resulting in reduced reproductive levels in a population. Statistics for each region include average age, most common sex, most common race, common injury types, per capita Incest rates, and more. At the very least, the average Dutch person has historically moved around more than the average Russianthe Dutch had colonies in the US, Africa, India, and Indonesiawhereas the average Russian peasant was tied to their land and would have married locally.

Inbreeding is reported to a 1960 base, and pedigree completeness is traced to ancestors born before 1970. (SKC) that when a dog is imported from another country, up to three generations of its pedigree (parents, grandparents and great grandparents) are typically included in the SKC database (Th.

As well, supporting the notion that some European countries possess distinct regional variation within them in how inbred their populations are, we have these pieces: For Britain (from traditional family systems in medieval britain and ireland | hbd* chick): And Spain (from here and here, respectively): Reinforcing the pattern we see across Europe and much of the world are the results of the Worlds Values Survey: The Northwestern European countries are in a group by themselves. Swedes are individualistic in the sense that they do feel any particularly family loyalty, but at the same time, like the Japanese (lots of similarities between Scandis/Finns and Japanese), they go with the flow of the group.

(^_^), @panjoomby the point is different genetic material is being inbred into each system so, different inputs (even with the same catalyzing inbreeding pattern/formula) may yield different results?. I dont mean that you will find a shicksa in every family tree. The isolation of a small population for a period of time can lead to inbreeding within that population, resulting in increased genetic relatedness between breeding individuals. Im beginning to think that youre a geek like hbd chick. Also, its worth noting that historic rates of inbreeding are just one selective force among many (not the least of which being the effects of manorialism, of strong states, and of internal population replacement ala Gregory Clark/Ron Unz) which act on a population (which may act synergistically to produce the traits we see), and close analysis may not reveal a perfect association between modern clannishness and historical rates of inbreeding, perhaps due to the vagaries of other selective forces that have been acting on these populations. Its about strong between family genetic barriers, not low overall genetic diversity (which matters little from a natural selection standpoint). In short, the more IBD, the more genetically similar the population is. Jews seem to think they are inbreeding. My guesses: Iceland is most inbred because the population is smaller.
