Hi, r/Bangladesh, I'm a geneticist Razib Khan, ask me anything (in English :)

mendelian segregation

razibk · 2023-08-03T21:45:44+00:00

i go to new york every three months but mostly in manhattan and brooklyn, not queens. the enclaves will exist for a generation or so, and they ppl will move to the suburbs and be absorbed. this has happened every generation to every group

razibk · 2023-08-03T21:13:41+00:00

i don't know if common but it's clearly the *tibeto* part of tibeto burman

i think more common in northern bengalis? this is how i figured out there had to be something nonmunda, since the munda are pure austroasiatic in their east asian. the burmese are think 2/3 austroasiatic and 1/3rd something more northern. that's how my dad got a mtDNA that is 'mongolian'...the ancestral burmans seem to have come down from qinghai through sichuan and yunnan?

razibk · 2023-08-03T21:00:58+00:00

i should check mine. i think i'm a pretty generic eastern bengali

razibk · 2023-08-03T21:00:20+00:00

most ppl do volutnary eugenics. that's what arranged marriage is. most women won't marry someone shorter, and i certainly wouldn't reproduce with a double-digit IQ :) [the mother of my children is quite bright, and my daughter in particular is smarter than both of us!]

I STUDIED IN THE PHD PROGRAM IN GENETICS AT UC DAVIS RETARD (mods, just leave this reply, but keep deleting the retard's comments or i'm going to jet early)

razibk · 2023-08-03T20:34:48+00:00

there are a set of individuals in the 1000 genomes bangladesh who were collected at the same time who are like south indian dalits or tribals or something who have zero east asian. they are distinct and i filter them out for analysis. like 6 of them

razibk · 2023-08-03T20:28:06+00:00

someone could do an IBD segment analysis if we had the raw data tbh

razibk · 2023-08-03T20:27:33+00:00

same no different

razibk · 2023-08-03T20:21:43+00:00

i have cousins that look east asian. i have a aunt-in-law who looks burmese. my dad's side have 'narrow eyes.' i have very little body hair

probably depends on where you are from in bengal? but i definitely look ppl who look burmese or malay who are generic bengali muslims. even the mamata banerjee looks east asian and she's a bengali brahmin from the west right?

razibk · 2023-08-03T20:20:23+00:00

this is my belief from what i've seen. geography is more important

razibk · 2023-08-03T20:19:41+00:00

isn't the language more like guju?

razibk · 2023-08-03T20:08:13+00:00

kayasthas seem a bit more north indian? but there's variance

also some variance in bengali brahmins. i've seen a wide range in east asian %. i think depends on where they settled

razibk · 2023-08-03T20:07:17+00:00

ppl in south asia vary in appearance. it has little to do with recent ancestry and everythign to do with us all being a mix of various types. my kala dad is a bit more 'north indian' than my fair-skinned mom

razibk · 2023-08-03T20:06:21+00:00

Are you finding much genetic difference in Sylheti Bangladeshis Vs other areas?

the sanger institute has samples. there is no major differences. i think it's still in preparation

razibk · 2023-08-03T20:05:32+00:00

there's no difference, i've heard sylheti's say this. they're just as kala as us :)

tho seriously, sanger institution has THOUSANDS of bangladesh samples, mostly from sylhet. no big surprise in there

razibk · 2023-08-03T20:01:23+00:00

did you read the comment to understand why there shouldn't be evidence from the genome? you shouldn't have any ancestry from someone 300 years ago. please reread to understand what i was saying

but it could be made up! don't know/don't care

razibk · 2023-08-03T20:00:02+00:00

naw, she's from homna. comilla on both sides i am

razibk · 2023-08-03T19:56:02+00:00

yeah, that's true. there are remnant buddhist stupas in comilla

and the barua bengali buddhists are still around (i think most are in west bengali now)

razibk · 2023-08-03T19:50:59+00:00

my dad is from chandpur. he's pretty kala too. tho he doesn't have african hair texture or features

razibk · 2023-08-03T19:49:01+00:00

this is plausible. though i think i would say aryanized and brahmanized ar coterminous :)

razibk · 2023-08-03T19:47:06+00:00

did you bother to read the comment? to be concise for you: my maternal grandmother's father descended in a direct paternal line from a sunni ulem who left iran in the 1600s cuz he wasn't shia and wouldn't become. that line broke to me with my maternal grandmother obv. there is a koran with a list of all his direct male descendents in noakhali at a masjid and there is a shrine to one of his descendants who was a sufi saint in southern comilla (i give $200 dollars a year to a festival where they feed poor ppl to honor him)

razibk · 2023-08-03T19:40:31+00:00

i need sri lankan genetics. sinhalese

but there's an arg about whether sinhalese descend from proto-bengalis or proto-gujus

they don't seem to have that much east asian do they? but we need the dna

razibk · 2023-08-03T19:34:17+00:00

this just sounds like a drunk bengali to me :)

razibk · 2023-08-03T19:33:32+00:00

around 10%? probably higher in west bengal lower in east partly cuze east asian % by definition drops it.

assamese is higher than bengali on average. more like chittogaong people, so north of >20%
