In the life of each of us the role of grandparents, paternal or maternal, has been fundamental to our growth. According to some scientists, however, there is an important difference between the four grandparents. Their studies have shown that the maternal grandmother is the one that most influences the training of nephews and the reason is to be found in the genes. Scholars have divided their research into 4 points about the relationship, so close, between grandchildren and maternal grandmothers.
1. Sharing of genetic heritage
In general, grandparents share less than 25% of their genetic heritage with their grandchildren. The DNA of the maternal grandmother, however, turns out to be the one with the highest degree compared to the others.
2 The bond is stronger
Because of the fact that the maternal grandmother shares more parts of her genetic code than the others, they have a stronger connection with their nephews, even from a psychological point of view.
3 They are mothers too
the maternal grandmothers mainly influence (25%) on the X chromosome of the nephews of both sexes, while the paternal ones transmit the X chromosome only to the grandchildren and not to the grandchildren. In addition, the maternal grandmothers are mothers themselves and, therefore, they share a motherly bond with their grandchildren.
4. The transmission of emotions
The latter theory, taken by the Chilean novelist Alejandro Jodorowsky, argues that in the process of sharing genes, mothers also transmit emotions to their daughters, who, as a result, will pass them on to their own, and so on.
Obviously, this study does not in any way say that the link with the other grandparents is not as strong and meaningful. The scientists who conducted this research mainly studied the genetic codes transmitted to other generations. All grandparents are special and unique in the lives of their grandchildren, and this is beyond doubt.
