"GOTRA" in HINDUISM Vs "GENE MAPPING!
Do you know why every time you sit for a Puja, the temple poojari asks you for your GOTRA ?
The Science behind GOTRA (Genetics), is nothing but what is today popularly known as GENE ~ MAPPING.
What is the GOTRA system ?
Why do we have this system of Gotras ?
Why do we consider the knowledge of one's Gotra to be so important to decide marriages ?
Why should only Sons carry the Gotra of father, why not Daughters ?
How/Why does Gotra of a Daughter change after she gets married? What is the logic ?
In fact, this is an amazing and ancient genetic science that we follow. Let's see the SCIENCE of GENETICS behind our great GOTRA systems.
The word GOTRA is formed from two Sanskrit words, GAU (meaning, Cow) and TRAHI (meaning, Shed).
GOTRA means Cow-shed.
GOTRA is like a cowshed protecting a particular male lineage. We identify our male lineage / Gotra by considering to be descendants of the 8 great Rishi (Sapta Rishi + Bharadwaj Rishi). All the other Gotra evolved from these only.
Biologically, the human body has 23 pairs of chromosomes (one from the father and one from the mother). On these 23 pairs, there is one pair called Sex Chromosomes, which decides the Gender of a person.
During conception, if the resultant cell is XX chromosome, then the child will be a Girl. If it is XY, then it will be a Boy.
In XY - X is from Mother and Y is from Father.
In this, Y is unique and it doesn't mix. So in XY, Y will suppress the X and the son will get Y chromosomes. Y is the only chromosome that gets passed down only between male lineage. (Father to Son and to Grandson).
Women never get the Y chromosome. Hence, the Y chromosome plays a crucial role in genetics, in identifying the genealogy. Since women never get the Y chromosome, the Gotra of the woman is said to be of her husband, and therefore changes after she is married.
They are 8 different Y chromosomes from 8 Rishis. If we are from the Same Gotra, then it means we are from the same root ancestor.
Marriages between the same Gotra will increase the risk of causing genetic disorders as same Gotra Ychromosomes cannot have crossover, and it will activate the defective cells.
If this continues, it will reduce the size and strength of the Y chromosome which is crucial for the creation of males.
If no Y chromosome is present in this world, then it will cause males to become extinct.
The GOTRA system is thus an ancient method devised by our great Maharishis to avoid genetic disorders and attempt to protect the Y chromosome.
Amazing bio-science by our Maharishis. Our Heritage is unarguably THE GREATEST.
Our Rishis had the "GENE MAPPING" sorted out thousands of years ago.
The logic behing prohibition of same gotra marriage gels perfectly with science.
Thanks to endogamy, Castes in india double as ethnicities. David Reich (2018) remarks (paraphrased) that the genetic distance (basically the variation that can be indexed) between two castes of same village in Hyderabad is greater than entire continent of Europe. This is because of endogamy.
Different castes in India have different ancestries. It is not even controversial. Its more or less a fact of population genomics.
What you’re looking for is “scientific racism”. You should have read my sources. Pubmed, science. Genetic studies helps to identify risk factors for groups of people, for eg Dawoodi Bohras have unique cancer mutation on one of their snps.
Genes help us to understand where did out ancestors came from. They also, very clearly show that because of 2000+ year of endogamy , most indian groups have become distinct genetically. So pretty please tell me wheres racism here.
Or is the lawyer brain so argumentative that you’ll defend your bad take till the end of time? [i too am a lawyer].
Open your horizons apart from law. Read the Reich book that I posted above .
Then come back and argue.
X comes from both sources (father and mother) so mostly it recombines taking features from mother and father both.
This gotra' system was made to glorify the race of the 'Brahmans' and patriarchy. Inbreeding depression was nowhere the issue neither there are enough proofs
However the "7"/"8" paternal haplogroups does not make any sense. India has many, R1a, R2, K2a, J2a, J1, H2a, C1-C2, I1 and so on and so forth. These are way more than 8. If you include subclades, then you will have hundreds.
Mitochondrial DNA is not very informative as it is inherited from mothers. In general parlance it is seen that it is usually the men who migrate in and out, and mtDNA of a population remains relatively stable with variance introduced in centuries.
