Again, I don't feel the need to be overly focused on the DNA aspects of this debate, but I will just add that they're trying to confuse the picture by going off on a tangent. Here's a brief summary of how DNA is used:
1) We inherit our DNA from both our parents, roughly half from each.. BUT there are TWO major exceptions
2) Our Y-DNA (from father to son) is passed straight on, and is NOT diluted.
3) Our mt-DNA (from mother to BOTH sons and daughters) is also passed straight on and is NOT diluted eiher.
4) Both Y-DNA and mt-DNA are subject to occasional mutations which are passed on to descendants. These markers are used both to identify people descended from the same ancestor, and are also used to group people descended from a common ancestor. Based on the number of markers used you can go from the present (siblings) to tens of thousands of years ago (e.g back to mankind's common ancestors).
5) This is the basis of DNA genealogy. These sets of mutations are used to group sets of population that share them together. They are known as Haplogroups.
6) There's a set of Haplogroups for Y-DNA and another one for mt-DNA
7) Occasionally a new mutation will arise, on top of the ancestral ones, which will show that one group is descended from its parent group.
8) No matter how many thousands of years pass, or how many male descendants I have, they will ALL inherit my sets of Y-DNA markers (plus the occasional mutation), no matter where they live or who they marry and they will show as my descendants, just as my own Y-DNA can be traced back to my ancestors. Likewise with their mother's mt-DNA.
This is how scientists for instance determine the peopling of the Americas. Based on their Y-DNA and mt-DNA the various native populations can be placed in certain haplogroups, and their distant ancestry traced back.
THIS CAN BE DONE FOR ANY INDIVIDUAL.
Either there is a conspiracy by nearly every DNA researcher, scientist, archeologist, paleo-linguist, most serious LDS academics, etc,, and they are ALL lying their teeth off, or else Mr Meldrum is wrong. I know which one is most likely.
