I think the number of combinations would be so high it would probably take thousands of times longer than the universe has existed for there to be a realistic chance of there being two people who just happen to have the same DNA.
My teacher is convinced that this is the case already. He thinks there is an even smaller amount of DNA combinations than current scientists believe, that as many as 2 in 600 000 people could be genetically identical. But that's just him....so, in short, yes.
the way DNA is formed is to put so random, you get mutations in the DNA of a cell, when that divids that will then pass it on good or bad, cross over of DNA, random which chromosome gets pulled to the different sides of the cell, and many more
Thered hve to be alot of people. way, way more than there are now. and if there was that many people, say in 10000 years time, DNA would have even more possible sequences through evolution. And if two were created, there would be competition and one of them would surely die of murder
evolution into two different form of human be more likely then running out od DNA combinations
DNA come in all lenght, some protain that are form for DNA are thousand on tousand of bases long
^^it sounds like it. Looking at the bigger picture if all the combinations had been used.
Its amazing to think that that is possible. (However unlikely) The concept is amazing.
Come to norfolk, only about 2 surnames here, not that many combinations of genes you can have.
