These have other origins which are not well understood as of now, including possibly the presence of HERC2 blue color trigger in recessive state.

"For Spanish Basques 25% 3,75 clear eyes......<br /><br />"For Spanish Basques 25% 3,75 clear eyes compared to French Basques 40% 16% clear eyes, I leave the response to Maju". <br /><br />It can well be, maybe depending on where exactly you sample. I'd use the terms Southern and Northern Basques however, otherwise people may get offended, as calling someone "Spanish" or "French" is considered almost insulting over here, at least by many people. Blue eyes are not too common over here: green, amber and grey eyes are at least as common (probably more) and then of course brown eyes tend to dominate. As blue eye alleles behave recessively, even if both my grandfathers had blue eyes (my grandmothers had them brown), among my siblings and parents nobody has blue eyes: brown, amber and amber-green only. Among my cousins there are a few with blue eyes but I would have to consider their other ancestors and I do not know them in many cases. I think these traits (blue eyes, blond hair, etc.) are more common in Spaniards overall. Probably Northern Basques too have them more commonly. So, yes, the data for Basques does fit (but not for Iberia).<br /><br />"For me, this shows the other laboratories have a better technic"...<br /><br />Can you mention any specific papers or other kind of reports?Majuhttps://www.blogger.com/profile/12369840391933337204noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-49963377061061245992013-07-06T14:12:01.547+02:002013-07-06T14:12:01.547+02:00"2) in the tree, ht9, ht10, ht15 and ht14 are..."2) in the tree, ht9, ht10, ht15 and ht14 are separate and parallel branche(s) from "West Eurasian" branch ht6 -> ht7 -> ht5 -> ht4 -> ht3 -> ht2,ht1."<br /><br />There is no such "West Eurasian branch" in the tree: how can you interpret the tree that way?! I'm flippant. If we call the main Eurasian branch E, as suggested bay me in the blogpost, then it goes as follows:<br />→ E1 (ht12)<br />→ E2 → E2a (ht6)<br />→ E2 → E2b → E2b1 (ht9 - Africa only)<br />→ E2 → E2b → E2b2 → E2b2a (ht7)<br />→ E2 → E2b → E2b2 → E2b2b → E2b2b1 (ht10)<br />... etc. <br /><br />What you call "West Eurasian" and the rest are totally alternating in their phylogenetic positions, and also all them (with the above mentioned exceptions) are common in Africa (or at least common enough in isolated African populations like the Biaka) and must have therefore an African origin. The only West Eurasian specific branch seems to be ht2 (and its offshoot ht1), although the Altai-American ht15 branch can also be considered that way by origin surely. All the rest are global or Africa-only. <br /><br />"But for me, the results for other samples with no determination of ht3-ht18<br />are not acceptable for ht1 andht2, specially for:<br />Kent 33%, 14% clear eyes, it is aberrant". <br /><br />It is indeed a strange result but I would not dare to challenge it without parsing the data. It may be caused by a fluke in sampling, or it may be that we have the wrong impression about commonality of blue eyes in Kent, or it may be that there are other haplotypes causing blue eyes. I did not comment but the data of 0% ht1+2 in many parts of Iberia is even more shocking. Granted that blue eyes are much less common than in the North but Andalusians and Galicians definitely have blue eyes with much higher frequency than 0%. <br /><br />Rather than challenging the data without personally reviewing it, I'd suspect other alleles being behind blue eyes in such populations, maybe even downstream of ht2-1 or maybe in other genes. <br /><br />"Utah-USA 51%, 25%, seems very weak for American WASP."<br /><br />They are not WASP: they are WADM: White Anglo-Danish Mormons. <br /><br />Anyhow, according to this map, Kent (and other parts of South and West Britain) has <50% of blue eyes (less than North French for example). Britain overall is probably not much above 50% on this trait. The center of "blue-eyeness" is an irregular oval around the Eastern Baltic, where frequencies peak to >80%. <br /><br />(More maps: <a href="http://origin-ars.els-cdn.com/content/image/1-s2.0-S1872497310000323-gr5.jpg" rel="nofollow">another map</a> but less useful: includes an "undefined" category but less data points in Europe; <a href="http://origin-ars.els-cdn.com/content/image/1-s2.0-S187249731100144X-gr2.jpg" rel="nofollow">another map</a> of pigmentation allele frequencies in Europe; <a href="http://1.bp.blogspot.com/-ubtHGbQwk40/UAAAxWBPOTI/AAAAAAAAABU/8ft5cQi9XIY/s1600/Light_Eyes_Map_.png" rel="nofollow">a color version</a> of Coon's "light eyes", not the same as blue, map). <br /><br />Notice that grey, green and amber eyes, which may be considered "light" are not blue, also some blue eye phenotypes are generated by other alleles. <br /><br />...Majuhttps://www.blogger.com/profile/12369840391933337204noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-51082512028734501602013-07-06T11:36:11.994+02:002013-07-06T11:36:11.994+02:003) Check out the column ND (Not determined) for Ke...3) Check out the column ND (Not determined) for Kent, Utah, etc. I could not determine the ht for those, this is why frequencies for ht1 and ht2 might be low...Palistohttps://www.blogger.com/profile/05633640722962576468noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-57848334226047569782013-07-06T11:34:03.214+02:002013-07-06T11:34:03.214+02:00!)

In the summary table I merged two data sets, the first data set is just focusing on ht1 and ht2 and is directly extracted from http://alfred.med.yale.edu/; the second data set is the one that I fully analyzed (based on HERC2 HGDP data Davidski provided).<br />This is why I gave two N's, "N total" and "N with ht3-18 data". Frequency of Ht1 and ht2 were calculated using "N total" (N of both data sets), for all other haplotypes I had to use the number of the second data set alone.<br />The table is basically a merged version of two tables. <br /><br />2) This was not my interpretation of the tree.<br /><br />3)The Swiss data is based on data at ALFRED.

I have been the same request.<br /><br />2) in the tree, ht9, ht10, ht15 and ht14 are separate and parallel branche(s) from "West Eurasian" branch ht6 -> ht7 -> ht5 -> ht4 -> ht3 -> ht2,ht1.<br /><br />3) A lot of results testing ht1 and ht2 only are certainly wrong, except maybe, the results with a dark bar (Swedes, Danes, German, Austrian Swiss, Galician) which seems me acceptable. I don't know Switzerland enough to know if it is acceptable that ht1+ht2=94% which gives 88,36% of the 16 sampled Swisses have clear eyes, according to the rule given by Palisto. Maybe also, this depend of the region(s) of the 16 Swisses. <br /><br />But for me, the results for other samples with no determination of ht3-ht18 <br />are not acceptable for ht1 andht2, specially for:<br />Kent 33%, 14% clear eyes, it is aberrant, at least for the local natives.<br />Utah-USA 51%, 25%, seems very weak for American WASP.<br />Tuscan is the most absurd : inacceptable partial test n=80 11%, 1% clear eyes; acceptable full test although weak number n=8 44%, 19,36% clear eyes.<br />The partial Spanish results (except Galician) are absurd, even if Spaniards have the brown eyes generally, clear eyes are not rare. For Spanish Basques 25% 3,75 clear eyes compared to French Basques 40% 16% clear eyes, I leave the response to Maju. <br /><br />For me, this shows the other laboratories have a better technic (it are able to test ht3-ht18 haplotypes) and also that tested all haplotypes, allows a cross-check and tested again if problem. <br /><br /> palamedehttps://www.blogger.com/profile/16915204988032336574noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-49532770332238214532013-07-06T10:14:51.939+02:002013-07-06T10:14:51.939+02:00This comment has been removed by the author.palamedehttps://www.blogger.com/profile/16915204988032336574noreply@blogger.com
