I inherit 1/2 of my DNA from each parent.
What happens to the other "half"?
1. Is it lost forever, and if so does that mean that if I had inherited the "other half" or portions in a different combination from my mother my mtDNA results could have been different?
If so, does that mean that portions of heredity can be "bred out" over generations?
2. If not, does that mean DNA is cumulative - all the genes are there all the way back except the sex specific ones?
I apologize to those who understand all this better than I. I'm trying to figure out what I will really know about my family history from all these tests I have paid for - especially since it now costs another $300 something to have it explained (and I don't know if after that I would know any more than I did before I paid for it).
