Hi Jen,
I've not got to the DNA part of the course yet. But looked into it a few years ago and my Dad agreed to give a sample. I was also blinded by science trying to understand it all (and still don't, if I'm honest) But I've tried to understand a small bitesized chunk with regard to the test he had done.
We did the male test, and I understand it is better to get the eldest male relative to give the sample in order for less 'mutations' of the dna. So my father's dna will be the same as his father, as his father, as his father etc. with only perhaps slight variation. This is why I opted for the male DNA test. I also, chose to do this now (as Dad is quite elderly) as I hope to understand more in the future and hope that the tests improve etc. over the years. At least this way I have a reference point in years to come. Our origins are Irish and I hope that having a dna test will assist alongside traditional sources to advance my paternal line research.
