As we know, our ancestors shouldn't be allowed to marry a guy or a girl with the same Bari. This practice is still followed even though it got outdated. There are so many such practices in Bunts Community. Nevertheless, everything has a scientific version but in the olden days, people believed in tradition and beliefs better than Science.
Scientific Reasons Behind Bari System:
What is Bari?
> The recognition and practice of human genetic lineages or the Lineage system (alternately known as Bari, Bali or Gotra system) among civilized ancient communities in India is distinctly older in origin and date than the caste system.
Why we shouldn't marry a guy or a girl with the same Bari in Bunts Community?
> Because two people with same Bari are considered as Siblings, So a marriage and further extension of Family may create Genetic defects because of the Duplication of Y chromosome, which means inbred children carry a high risk of being born with recessive genetic mutations. If they had kids, there’s a good chance they wouldn’t be healthy; and even if they were healthy, they would still likely face bullying from their peers for being high-profile children of incest.
Two people with the same Bari are considered as Siblings! What's the Logic Behind this?
> As per Science, Chromosomes, and Genes:
Humans have 23 pairs of Chromosomes and in each pair, one Chromosome comes from the father and the other comes from the mother. So in all, we have 46 Chromosomes in every cell, of which 23 come from the mother and 23 from the father.
Of these 23 pairs, there is one pair called the Sex Chromosomes which decide the gender of the person. During conception, if the resultant cell has XX sex chromosomes then the child will be a girl and if it is XY then the child will be a boy. X chromosome decides the female attributes of a person and Y Chromosome decides the male attributes of a person.
When the initial embryonic cell has XY chromosome, the female attributes get suppressed by the genes in the Y Chromosome and the embryo develops into a male child. Since only men have Y Chromosomes, the son always gets his Y Chromosome from his father and the X Chromosome from his mother. On the other hand, daughters always get their X Chromosomes, one each from both father and mother.
So the Y Chromosome is always preserved throughout a male lineage (Father – Son - Grandson etc) because a Son always gets it from his father, while the X Chromosome is not preserved in the female lineage (Mother, Daughter, Grand Daughter etc) because it comes from both father and mother.
The Bari system was designed to track down the root Y Chromosome of a person quite easily. If a person belongs to Kundarannayya Bari then it means that his Y Chromosome came all the way down over thousands of years of timespan from the Kundarannayya Bari! This also makes it clear why females are said to belong to the Bari of their husbands after marriage. That is because women do not carry Y Chromosome, and their Sons will carry the Y Chromosome of the Father and hence the Bari of a woman is said to be that of her husband after marriage.
The Y Chromosome is the only Chromosome which does not have a similar pair in the human body. The pair of the Y Chromosome in humans is X Chromosome which is significantly different from Y Chromosome. Even the size of the Y Chromosome is just about one third the size of the X Chromosome. In other words throughout evolution, the size of the Y Chromosome has been decreasing and it has lost most of its genes and has been reduced to its current size. Scientists are debating whether Y Chromosome will be able to survive for more than a few million years into the future or whether it will gradually vanish, and if it does so whether it will cause males to become extinct!
Y Chromosomes can exist only in an XY Combination and X cannot mix and match with Y except for a small 5% of X which matches with Y, while the remaining 95% of Y Chromosome which is crucial in the development of a male have absolutely no match at all!. It is this 95% of the Y Chromosome which is completely responsible in humans for creating a male or a man.
So in order to prevent the degradation of Y chromosome and have sufficient Men in Bunts Community, Our ancestors have devised the Bari/Bali System.
