It is one of the most hidden questions but, at the same time, one of the most questioned. Especially in the most personal areas. Many families doubt whether this or that skill will have been inherited from the parents, so we must also take into account if the DNA it would have something to do with the studies. This question has not been studied specifically, but it has been studied indirectly. And yes, DNA has a lot to do with student abilities.
Keep in mind that in the DNA of each person is printed all their character. And that also includes their ability to study, memorize concepts and do the work that the teachers themselves put in. There is no doubt that this aspect has a lot to do with the results that the student later obtains.
On the other hand, by this we do not mean that DNA will mean success or failure, depending on the results that the parents have achieved. There are many cases in which the parents have been very successful, while the children have none. Or otherwise. It would not be bad for you to take a look at the profiles that we have already been able to know.
In short, know that DNA has a lot to do with the results and the abilities of the students. It is not a whole, but it is one of the concepts to take into account. The next time you see the notes your children have had, check if the same has happened in your family.
