i wonder why a very old haplogroups such as A, or B or C, D is rare comparing with R or even a branch of R


are there any estimation of how common are the Y haplogroups in the world

I get what you're trying to get at here but you're of Y-DNA A, bro. We all are. As in, essentially every Human male out there belongs to a subclade of Y-DNA A. E-V32 and R1a are both ultimately subclades of Y-DNA CT (https://yfull.com/tree/CT/) which is a subclade of Y-DNA BT which is a subclade of Y-DNA A1b which is a subclade of Y-DNA A1 which is a subclade of Y-DNA A0-T (https://yfull.com/tree/A0-T/). As for B, C and D... People can make some guesses for you based on modern phylogeny + frequencies and perhaps what they feel are archaeological and modern autosomal DNA patterns that go with them but we can't fully grasp how these Haplogroups ended up the way they have without sufficient ancient DNA, I guess.

Sure, can't be hard to notice any Y-DNA Haplogroup's currently known frequency with some googling.

yes i know we all are a branch of A and B and CT

i want to say .. why one branch of the tree is very long .. the other is not ??
if we take A haplogroup example .. the branch of the A1b is the prevalent .. the equivalent branch is not .. although it take the same long time

is there a possibility of wrong assignment of some haplogroups ..

i read an article in the internet predicting that A haplogroup is not old ?? and E & R for example is older than it could be and more complicated
this making me confused ..

i actually searched the net about world percentages .. but i thought i can get a research-based percentages from the researchers here

thank you

maybe

https://en.wikipedia.org/wiki/Haplogroup_O-M122

or another Chinese marker

Thats easy math, either indians or chinese, and knowing indian hgs are more diverse I would probably go for chinese O as stated above. As to most widespread its probably R1b

I think O is accepted as the most common top level branch. Not sure if R1b is more widespread than O, depends who counts. I'm sure there are more Chinese in Scotland than vice versa.

O is too general, like E, divided itself
on couple of separated paleotribes.

Probably R1 is the most common, 22.7% of world's population.
(Considering for India 30%).

If R2 would have also IE origin, then adding it, it will be 25%.
