We all have a special connection with our grandmothers. They are synonyms of love, honesty, kindness and endless wisdom. Your grandmother will give you some of the most important lessons in life. According to them, it’s all about the small stuff.
For your grandma, a pack of freshly-baked cookies is much better than a new car.
Grandmothers play an important role in children’s life. However, maternal grannies have “different powers” as explained by scientists. Some theories claim that paternal and maternal grandmas have different impact on their grandchildren.
Genes are primary units of heredity, and we get them from our mom and dad. They contain DNA material which is split into chromosomes. Each of us has a pair of 23 chromosomes – one from mom and one from dad. The last pair of chromosomes is different, and it depends on the gender of the child. The other 22 pairs are identical.
Science reveals that 50% of our DNA comes from our father, and the other half comes from our mother. In other words, we share $25 of our DNA with our grandparents.
Female children have two copies of the X chromosome, and boys have one Y and one XX chromosome. This actually determines baby’s gender.
Maternal grandmas pass on 25% of their X chromosomes to their grandsons and granddaughters. Paternal grandmothers pass on one of their X chromosomes to their granddaughter, but they don’t pass and X-chromosome on the boy.
What’s the point of this brief introduction?
Biologists believe that closer genetic bonds affect the behavior of your grandmother. The “Grandmother Hypothesis” suggests that post-menopausal women help grandchildren to live longer.
Anthropologist Leslie Knapp and the team confirmed this theory. They studied birth and death records in seven major populations. The team went all the way back to the 17th century. They zeroed in on infant mortality rates and maternal grandmothers.
The results showed that the effect of maternal grandmothers on children is affected by the generic relationship they have. It’s all about the DNA.
Unlike paternal grandmothers, maternal grandmothers have better genetic relation to the kids. This doesn’t come as a surprise. Mothers care more for their sons than their nephew. They care more for her sister than her cousins.
Chilean novelist, essayist, and playwright Alejandro Jodorowsky, explains that we have a strong connection with our maternal grandmothers. According to him, our genes probably “skip” a generation and are directly passed to grandchildren.
That’s why some kids look and act like their grandparents. Mothers pass on emotions to their girls, and they pass them on to their kids.
Jodorowsky went on explaining that the emotions grandmothers had during the pregnancy with their daughters are actually passed on the baby and probably to every future grandchild.
This sure made us think and ask questions. We’ve already noticed some of these signs. Science can take us places, and we can’t wait to learn more about this particular topic.
