Well, I dare to say that in certain cases the haplogroup and a certain type of habitus generally connected to the haplogroup in guestion don't necessarily correlate (it would actually be interesting to see a "median habitus" of hg-N3, so common in here). My grandfather (father's side) originates from a region rich in N3, which indicates that about 80%? chance I should be also N3 (Tat-C). Yet the autosomal (50/50 from mother and father) genes are different in the way they pass on from generation to the next. For instance the "case Grigoriyev" (welcome to the forum, by the way!/добро пожаловать!) is O3, but just look at the picture (he could pass as any regular guy here in Finland for example). Another example is an ex-co-worker of mine (the father from Trinidad and Tobago): his two sons (3rd generation, Finnish mother) are as pale as everybody else here, but the hg-y should be something like an African one. My point simply tries to be, that haplogroups can only tell with whom you share your forefathers (or mothers in case of mtDNA). The autosomal genes make you look as your parents do (more or less). As thousand of years have passed by, the autosomal exchange of genes have done their work nation-wide, but the haplogroups stay pretty much the same, unless a new mutation occures in the mean while... But to my final guestion: is there actually a correlation between certain Y-haplogroups and the type of beard growth (colour, texture etc...) (Just as a "poor man's Y-hg-test")? If I'm not totally wrong, the beard-gene is located to the Y-chromosome? (or then not?) |
