Dowling DNA - by Brian Thomas Dowling (1955 - )  

DNA BAnner


I have had my DNA tested with the three main tests, 'Y-DNA', 'mt-DNA' and 'at-DNA'.

Test What Tested Result for Haplogroup (group who share a common ancestor) Diagram or notes
Y-DNA tests the male genhome. 

Father's father's father, etc. and so on back until genealogical Adam! (nothing to do with the Bible).
The cell's nucleus has 23 chromosomes.  This tests one half of the 23rd chromosome used to determine gender.  Only males have this DNA tucked away in the nucleus of a cell.  I got this  from my father and it has hardly changed for many generations. (in a male this pair of chromosomes is X & Y, in a female it is X & X, so women cannot be tested for this Y-DNA). R-FGC28340

mt-DNA tests the female genome.

Mother's mother's mother, etc. and so on back to one of the genealogical Eve's (nothing to do with the Bible)
Males and females all have this, and mine comes from my mother.  Mitachindria is found in the material surrounding the cell's nucleus and has lots of detail.    K1a11  
at-DNA tests automes.
Also called the Autosomal test.  FamilyTreeDNA call it their 'Family Finder' test.  Many other companies, who only do one type of test, are a little misleading by only refering to it as their "DNA test" suggesting it is the only test when it is only one type of test.

Generally has part of DNA for both parents, both sets of grandparents, great-grand parents, and less-accurately, great-great grandparents.

This test can include a test for some 'X' information but this tricky to interpret right now.
This is a test of 22 of the 23 pairs of chromosomes called autosomes. 

Males and females have this but its all a bit muddled up as to which bit comes from the mother or father.  As a result it is not so good for tracking a male or female line.  However, it is really good for recent ancestors to 4 or 5 generations back on both sides. 

Not so accurate for deep ancestry (use 'Y' and 'mt' for that). 
Sometime may make a poor guess at haplogroup
