What can DNA tests really tell us about our ancestry? - Prosanta Chakrabarty

Maybe Neanderthal and modern humans are actually the same

What's french dna?

I suppose it was silly of me to think that all people were represented in the database already. Of course some might not have the opportunity to contribute and some might choose not to.

Also dna is inherited randomly

Go back further and you get different results, still useless, just different.

My sister and I have something similar. We have the same parents but my mom has latent genes from African ancestors and Native American ancestors. I inherited these genes but my sister did not.

❤. 😅. 😅. 😅. 😅😅❤

🥱

Can someone accidentally find out that their biological father is their uncle through an ancestry dna test?

I am Ashkenazi Jewish
And This Is My DNA Result
I have 80% khazar DNA🧬
10% European DNA, and 3 other dna

Ancestry tests => X

They will know after life if they worshiped the true God.
God will help the people who worshiped him alone without associating any partners in worship.
God eloh/Alah/Allah

Even though DNA tests don't tell you everything, I did find out that my great grandfather (paternal) wasn't my great grandfather meaning my last name isn't even legitimate

Does this mean my MyHeritage result could change overtime?

Can light color rendering index decoded true ages , DNA , and original ancestry that í why people introduce eye glass to kept true identification from being decoded from optometrist

I lowkey wanna try to get DNA tested but i heard that they can steal ur personal info or smt

Wow, this explains so much 😵💥

Amazing video!

Makes so much sense but I never thought about it that way. Thank you!

Yea dna testing for ancestry is pseudo science. Don't buy into the nonsense.

They really not stop using the term ethnicity and switch to regionicity.

Im born Canada, native Ojibwe.

Was then very curious, i took ancestry and omg, i can't say im full blooded native, i have to bloodlines straight from france traced another from scotland.

Did some history...dna is crazy.

I just got a DNA test turns out I'm...
well I have no idea.

Does ancestry gene disappear, and changing?

My parents aren’t the same ethnicity so my siblings and I look all different

Me, being a Bengali dude, searching the internet for the best commercial DNA tests for Bengalis, South Asians or Indians, and here is a Bengali dude of similar ancestry raising doubts in me about it, which I already had. Kind of, ironical.

The following is the doubt which I had before the video and to an extent even now :-

So they do the prediction of an origin based on if a percentage of other test takers in the database said they come from that particular origin. But that is not going deep into the ancestry and also it can be extremely inaccurate since the test takers in the database might have different ethnicity than the country's people or might give inaccurate information especially of a community who themselves don't know their origin beyond few generations. I know the chances of that get lesser if more and more test takers come up but even then it might be a possibility that a lot of them wouldn't know who their ancestors beyond 4 generations. Do they match the DNA results with ancient remains of tribal people or people beyond few generations at least to the previous millenium ? I have seen many such videos but nobody has touched on these points in this way much.

Me, as a Bengali guy, wants to know how much percentage of my ancestry is from Indo-European, Iranian, Indian tribal, Mongolian, East African, West African, Middle Easterns, Cental Asian or Eastern European (that might be predicted by Indo-European percentages), and of course lastly, other Indian communities assuming a tiny bit of difference between Bengalis and non Bengalis in the Indian subcontinent especially in mainland India. Even amongst Bengalis, there would be differences in DNA based ancestries especially between Muslims and Hindus, or let's Eastern most Bengalis like Tripura people or Western most ones.

Even if database of such websites are full of Indians, still they might only show that I'm South Asian, Indian or Bengali. However, I know, some wesbites do show the early and deep ancestries like the Indo-European, Iranian farmers, etc, as I mentioned above, even categorsing patrilineal and matrilineal ancestries based on Y-DNA and mtDNA respectively but I am not sure how do they do that, how precise they are, how far back they go and how do they assume what markers belong to what ? These were or are my questions/doubts regarding this.

Meh. Yes, recombination. As you say, that removes the guarantee of equal representation of my ancestors in my DNA. Then you play the game of, imagine this would not happen - and come up with fractions that imply equal representation. That is not true either. As 50% of my chromosomes (the things consisting of DNA) is from my father and 50% from my mother, there is no guarantee that I will pass on half of mother's chromosomes and half of father's. I will pass half of my 46 chromosomes - 23 chromosomes on and these 23 can be predominantly from father or predominantly from mother. With or without recombination.
The only fixed fraction we can be sure of is the fraction of our mother and father - 50% each (if nothing goes wrong as in Down's syndrome).

I think some of the people in the comments need to re-watch this video

Yes

What is extremely concerning is what those business will do with the data they harvested.

So it's a bit misleading in finding your ancestry? but if i wanted to find out what the genectic makeup of my dna?

transplant, serrogate mother

I love France 🇫🇷

The animated thursday clasically juggle because salad noteworthily present via a amused frame. ajar, cute violin

why is this video's animation pixeled :D

What I learned: Elizabeth Warren may have actually been telling the truth about her being descended from native Americans.

Why don’t they call them gametes anymore?! Lmao did my bio education screw me with useless outdated info -.-???

I thought human/neandethal offspring were infertile?

so if i have french fries for a year . So will I be dutch?

DNA, Genetics, Ancestry, Lineage, Heritage, Heredity, Markers, Clusters, Chromosomes, Highlights, And Genomes could give us plenty of backtracking yeah

I hear that diarrhea is hereditary. It runs in your jeans.

So basically these DNA/Ancestry tests are useless. If you go back 10 generations you are talking about 2000 different "relatives" and all their signatures can't appear in our own DNA. Hominids/humans have been "mixing" for thousands of years so we should have a bit of everything in all of us.🌐
