Genetic inheritance - Working backward in time
This is a very theoretical question.
In theory, if everyone agreed and we DNA tested all 7 billion people on the planet today, could we mathematically work backward to figure out the EXACT DNA code of all our past relatives?
So in theory, pretend we don't have a DNA sample from any of my past relatives, could we predict with 100% certainty what the DNA code of my dead father, or grand father, or great grand father, or great great grand father, etc, etc, would be? Would this be 100% accurate?
In theory, all 7 billion of us must have a common ancestor, the theoretical Adam and Eve. Even if Adam and Eve never existed, we all still had to pass through a very small population of people.
In theory, how far back could we predict just through DNA testing all 7 billion people today?
{Lets assume that the DNA samples we take today would be the full 3.2 billion lines of code. And let's assume there are zero mistakes, zero error}
