What can DNA tests really tell us about our ancestry???🧐 Courtesy TED Ed , Prosanta Chakrabarty ( American ichthyologist and associate professor of ichthyology, evolution and systematics at Louisiana State University) Two sisters take the same DNA test. The results show that one sister is 10% French, the other 0%. Both sisters share the same two parents, and therefore the same set of ancestors. So how can one be 10% more French than the other? Tests like these rely on our DNA to answer questions about our ancestry, but our DNA actually can’t tell us everything about who we are or where we’re from. DNA tests are great at answering some questions, like who your parents are, but can provide baffling results to others, like whether you have ancestors from a particular region. To understand why, it helps to know where our DNA comes from in the first place. Each person’s DNA consists of about 6 billion base pairs stored in 23 pairs of chromosomes- 46 total. That may seem like a dizzying amount of information, but 99% of our genome is shared among all humans. The remaining 1% contains everything distinct about an individual’s ancestry. Commercial DNA tests utilize less than 1% of that 1%. One chromosome in each pair comes from each parent. These halves join at conception: when a sperm and egg, each with only 23 chromosomes, combine. The story of our ancestry becomes muddled before conception. That’s because the 23 chromosomes in a sperm or egg aren’t identical to the chromosomes of every other cell in the body. As they go from a cell with 46 chromosomes to a sex cell with only 23, the chromosomes within each pair swap some sections. This process is called recombination, and it means that every sperm or egg contains single chromosomes that are a unique mash up of each pair. Recombination occurs uniquely in each sex cell- making two sisters’ chromosomes different not only from their parents’, but from each other’s. Recombination happens before conception, so you get exactly half of your DNA from each parent, but going further back things get more complicated. Without recombination, you would get 1/4 from each grandparent, 1/8 from each great-grandparent, and so on, but because recombination happens every generation, those numbers vary. The more generations removed an ancestor is, the more likely they won’t be represented in your DNA at all. For example, without recombination, just 1/64 of your DNA would come from each ancestor six generations back. Because of recombination, that number can be higher, though we don’t know for sure how high- or it can as low as 0. So one sister isn’t more French in the sense of having more ancestors from France. Instead, the French ancestors are simply more represented in her DNA. But the story doesn’t end there. Tests don’t trace the DNA of the sisters' actual French ancestors- we don’t have access to the genomes of deceased individuals from previous generations. Instead, these results are based on a comparison to the DNA of people living in France today. The tests look for genetic markers, or combinations of genetic markers. These markers are short sequences that appear in specific places. The sister deemed "more French" shares genetic markers with people currently living in France. The assumption is that these shared markers indicate ancestors from the same place: France. It’s important to note that results are based on people who’ve had their genomes sequenced- 80-90% of which are of European descent. Many indigenous peoples are barely represented, if at all. The test won’t reveal heritage from people not represented in the database, and shouldn’t be used to prove race or ethnicity. And as more people get sequenced, your results might change. Looking further back, you may get a result like 2% Neanderthal. Though Neanderthals were a separate species from humans, that 2% doesn’t come out of the 99% of our genome shared among all humans, but the 1% that varies. That’s because about 40,000 years ago, certain human populations interbred with Neanderthals, meaning some people alive today have Neanderthal ancestors. Many Neanderthal ancestors, in fact: there are so many generations in 40,000 years that a single Neanderthal’s genetic contribution would be untraceable. You can be both 100% French and 2% Neanderthal- though both come from the 1% of DNA that makes us different, they’re accounting for different things. Looking for traces of our ancestry in our DNA gets complicated very quickly. Both the way we inherit DNA and the information available for testing makes it difficult to say certain things with 100% certainty.
Hai can anyone explain to me who are knanaya catholics ???? What rite do they follow??🤔 According to me threre are only 3 catholics in kerala Syro malabar catholic- liturgy rite east syriac rite, classified under eastern catholic. Syro malankara Catholic- liturgy rite - Malankara rite, classified under eastern catholic. Roman Latin catholic - liturgy rite - Roman rite, classified under Roman catholic. "It is belived" St Thomas came to kerala in AD 52 nd through his evangelistic activities, he created " St. Thomas Nasrani", later in the year 1653 coonan kurisu Satyam took place in mattancheary, they re- converted to catholics by Portuguese which end up to became syro malabar/ malankara Catholics. St francis xavier came to india the year1542 may 6th nd spread christianity in Goa kerala and may other coastal part of India. Which end up to become Roman Latin catholic.

Various other DNA service providers have done their own population studies and all of them are very clear, very conclusive.. and it 100% validates the stories that some have known all along. "The Suddists/southist people were historically washermen who came from Tamil Nadu. In those days, ash was used to wash cloths and vessels. Both men and women from this community worked as washers. Since they had a habit of tying ash on the tip of their cloths, they were called as “Chaaramkettys” (Ash tiers). Northists (St. Thomas Christians) did not consider Chaaramkettys as Nasranis. They were mainly considered as a lower sub-caste of Nairs. Since the Chaaramkettys mainly worked near “Kinar” (Wells) and ponds, they were also called “Kinar Nair” (Well Nair). It was this “Kenar Nair” which later Syrianized as “Knanaya”. The Chaaramketty people spoke Tamil language. They are believed to be a branch of Vellala Chettys. Various Grantha Variyolas have references of the arrival of Chaaramkettys from Tamilakam. Chaaramketty women wore mainly Tamil-styled cloths like Saree, etc while Nasrani women strictly wore Chattayum Mundum. Besides these, Chaaramketty women used to have many other habits which Nasrani women did not have, such as wearing jasmine and other flowers on their hair, nose-piercing ornaments (Mookkuthi), etc."
Professor T . You are prophesying things differently. Ignorance of history is the main cause of Sudhists. All their leaders and the so called”Knanites “ which they use as adjective always certify “345” A D as their landing. No historical evidence or proofs from Vatican Archives or from Indian Archeological study prove this foolish story. This is from reliable sources which could be proved on demand. And about the D N A proof from U S and Canada of Knanites proved 98.7 percent Dravidians.
Have you seen native arabs, they have dark complexion, have you seen brazilians they have complexion from dark to very fair, same like that knas have different coloured people
There should be b a proper evidence to argue with your points.or else it will end as a cooked up Stories. Don't b a bunch of jockers. I am from kochi there r real Jews who is been accepted with genuine evidence from our country and there Native country, thatz the power of truth... this is 21st century everybody have commansence to think. So plz 🙏
I heard the story of this ashes from my father. He told me that there was a quarrel between thekkumbhagar and vadakkumbhagar and a church of thekkumbhagar was burnt by vadakkumbhagar. They took the ashes and kept in the madiseela of their loin cloth
@Chack In our area the Thekkubhagar were called charamkettikal in a denigrating way because of the as thing and they are not considered by others as respectful as vadakkumbhagar because of their booze habits and inbreeding and some customs that look funny nowadays. Another thing, the Christians of Kerala is a heterogeneous mix and it applies to all denominations. Nothing wrong with that too. Anyway, we got the status in Kerala due to those Syrian migrants only.
