You have to do your own growing no matter how tall your grandfather was.
-- Abraham Lincoln (1809-1865)
You have to do your own studying, learning and researching no matter how scholarly, well-learned and well-respected your grandfather was.
Since I joined Institute of Education (now call National Institute of Education) in 1982, I have the opportunity of meeting many scholars, professors and researchers who are outstanding, well-learned and well-respected in their field of studies.
Nevertheless, knowledge and learning is something you cannot acquired automatically like DNA or gene. Their children's academic achievement, may benefited from their good examples, yet is not acquired through hereditary system.
If you fortunate enough to have someone renowned and knowledgeable as your parents or grandparents, it will not make your learning effortless.
What they can provide you are their wealth of knowledge with a library of good books at home for your convenient and easy access.
You can only make them yours through your own study, reading, researching and synthesis.
Hereditary system only work in turn of material goods, you will inherit from them and unearth them through your own work.
They can only provide you the library, not the knowledge!
