A race shares genes?

'Jews all share a certain gene': German banker Thilo Sarrazin sparks outrage | Daily Mail OnlineHere's a recent article about some german banker who says that jews share a certain gene. Understandably, it sparked outrage and indignation, but this thread is not about anti-Semitism or anything of that sort.I'm just wondering whether its such a far-fetched idea that all races share certain genes. If races usually share certain phenotype, wouldn't it make sense that they share certain genotype as well? Edited by Ragged, : No reason given.

Thanks for getting the right link, sorry about that.But wouldn't a non-religious person of Jewish decent (both parents Jewish) still be considered a Jew? Isn't that both a religion and ethnicity?

how about Caucasians, Africans or Asians? They all have very distinct physical similarities which are not shared with other races. would that be safe to say that they have a genetic make-up unique to their race?

I'm not implying that all representatives of the same race look the same (or even close), but I am implying however that you could never confuse a person of an Asian race with a person from, say, an African race. What this amounts to is that there could be alot of genetic diversity between representatives of the same race, but at the same time they could share a certain gene/allele which would only be found in their race.A person of African descent would look distictly different from a person from Northen European descent. Those differences no doubte arose from differences in genetic makeup of the peoples. It would make sense that different races (or whatever you want to call them) of humans share certain genetic make-up unique only to that race. Or atleast a preponderance of that genetic make-up would be found in that race.

Of course when races interbreed genes get shared and it can be difficult to tell which race a person has as ancestors just from physical characteristics since traits have different degrees of dominance. For example, in the top picture the girl definately has African ancestry even if its mixed with something else. The bottom picture is more difficult, but I would guess that there is some Arabic blood involved . There is room for confusion in both cases no doubte. But you could never confuse a pureblooded Japanese person with a pureblooded Spaniard.Yes, the distribution of some alleles probably have a more scattered distribution than could be explained by geography and race, but it seems reasonable to me that some traits are unique to a particular race. Even more so, peoples of the same general race but inhabitants of different historical countries (i.e China, Japan) have distinctly different appearences. Why would that be if there was nothing unique about their genetic make-up?

That Philippine girl has African blood in her, even if it is mixed with Asian blood. And I know this simply by looking at her. Because of colonialism and travel we have people of different races live in different places. Just because a person of European descent was born in South America, it does not make him latin.
