    Question Do haplogroup mutations usually just occur in only one, or a whole population of sperm cells inside the father's testes?

    Thanks. That's interesting, because on Wiki it says the haplogroup mutation only happens in the sperms. Do you have any source for the studies about this?

    Question Do haplogroup mutations usually just occur in only one, or a whole population of sperm cells inside the father's testes?

    I have been wondering about this for so long. Do those haplogroup mutations usually only occur in ONE of the father's sperm cells? So you can have two brothers in the same family carrying two different Y haplogroups, even if they are biological brothers by blood, both paternally and maternally...

    What was Assyrian Empire royal Y-DNA?

    We don't know for sure as there are no burial sites for Assyrians monarchs available for DNA analysis. I am only speculating them being the descendants of Steppe nomads because that is the case in most of the royal tombs and archaeological sites found in Central Asian and Middle Eastern...

    What was Assyrian Empire royal Y-DNA?

    I think the citizens could have high J2, but the royals and nobles are likely R and Q or other steppe nomad haplogroups.

    Question How does a new Y-dna haplogroup appeared?

    The haplogroup defining mutation usually only occur in ONE of the father's sperm cells? So you can have two brothers in a family carrying two different Y haplogroups even if they are biological brothers both paternally and maternally in every way? For example, there was a man with haplogroup K2b...

    Question How does a new Y-dna haplogroup appeared?

    The haplogroup defining mutation usually just happens in only ONE of the father's sperms? Or it usually occur in a whole population of sperm cells inside the father's testes that affects multiple sperms?

    Question Viking warriors haplogroup and Nordic culture

    So, I read some posts on a non-english forum that say the people from Central Asia created the Nordic culture, as Viking soldiers and elites actually belong to haplgroup R1a and haplogroup N, the Nordic runes derived from old Turkic scripts, and even the Yggdrasil tree in the Norse mythology is...

    Do you believe that Y-DNA influences looks and behaviour?

    Is there any studies show that there are genes on the Y chromosome with the function to determine the maximum growth potential limit of height, frame, jaw, muscle, and brain in a person?

    Do you believe that Y-DNA influences looks and behaviour?

    Wait, isn't Nikola Tesla's haplogroup R1a?

    Do you believe that Y-DNA influences looks and behaviour?

    Hmm the son being shorter than the father is not a common occurrence, I don't think this has to do with the Y chromosome. In my opinion, I believe the Y chromosome doesn't affect physical appearance at all, but it has greater influence on the psychological traits like personality and behavior...

    Do you believe that Y-DNA influences looks and behaviour?

    By "Appearance influences" do most of you mean the structural change of the body due to the levels of testosterone production controlled by genes on the Y chromosome? Do you think the only correlation between the Y chromosome and physical appearance is the level of testosterone production in...

    Do you believe that Y-DNA influences looks and behaviour?

    Do you have the source for such study that says the Y chromosome has genes that directly determine height growth and physical build of a person(which the effect is not through testosterone level or the autosomal genes that people from that specific Y haplogroup usually carried)?

    Question Could it be possible for members from different species like cats and dogs to share the same haplogroup?

    I see, thank you so much for the reply mate. What do you think of common haplogroups shared by subspecies within the same specie? For example Polar bears and Brown bears, African lions and Barbary or Asiatic lions, Siberian tigers and Bengal tigers, etc. Do some lions today carried the Y...

    Question Could it be possible for members from different species like cats and dogs to share the same haplogroup?

    Recently thought of this wild hypothesis: although the cats(feline) and dogs(canine) we see today are two totally different species, there actually existed a common ancestor which both felines and canines descended from known as the Miacidae, or the Miacis, a small, weasel-like insect-eating...
