World.-according to the Chilean essayist, Alejandro Jodorowsky, women inherit their genetic information and temperament from their maternal grandmothers, this statement is supported by a study conducted by the National Institute of Environmental Health Sciences with Headquartered in North Carolina, United States.
Jodorowsky explains in his book called “Metagenealogy: Self discovery through the psychomagic and family tree”, the genetic influence that maternal grandmothers have on their granddaughters. According to the Chilean, the genes they receive in the mother’s womb come directly from the grandmothers.
In a study published by the National Institute of Environmental Health Sciences, it was observed that OVA transmit more genetic load and mitochondrial information. Although sometimes it is not so much the physical resemblance with the grandmother, psychologically it would be and in the long run, the grandchildren adopt certain behaviors and the temperament.
According to the theory of Jodorowsky, it seems that since a woman conceives a female fetus, already contains the number of oocytes that will be released in OVA in adulthood, from here are transmitted genetic values from generation to generation on the female side, being Always the maternal grandmother to transmit to her granddaughters her biological inheritance.
Those emotions that Grandma suffered when she was pregnant with her daughter were passed to her and perhaps perhaps to those future granddaughters, according to Jodorowsky. That is, that emotional influence can still be active in the DNA, even if a generation has already passed.
As is known, the information of mitochondrial DNA, that is to say the one that comes from the mother, is greater at the time of the embryo formation. The father’s sperm lacks this kind of information, so paternal grandparents don’t intervene any further. In spite of this, some genetic studies estimate that the traits of the father’s DNA are much more dominant in relation to heredity.
On average, human beings share roughly 25 percent of their DNA with their grandparents. Researchers from the University of Cambridge published research related to the link between the maternal grandmother and her grandchildren. According to their research, this connection occurs due to the X chromosome. Maternal grandmothers will pass 25% of their X chromosomes to all their grandchildren, allowing them to inherit their genes. However, paternal grandmothers only transmit their X chromosomes to their granddaughters, but not to their grandchildren. So, while paternal grandmothers have a 50 percent relationship with their granddaughters, they have a 0% relationship with grandchildren.
