DNA profiles are just the genetic make up of that particular animal. No two profiles are the same, because each dog, even littermates, are different and will have a different signature. Like human DNA. The letters are labels and it is very interesting to see how many show up across the breeds. I study this a lot. For example: I have two littermate sisters, both DNAíd...the report is very similar, but not exact. One dog barks in the pen, one does not. Is that the difference...who knows. The DNA today is used to prove parents, because letís say a reproducing stud dog dies or goes sterile that a person has been selling high dollar pups off of and you want that to continue...with out DNA to prove it, you could just cover those females with his brother and keep rolling. It has happened before.

Back to the original. Those letters are that dogs signature and the blanks are either non detected areas or non tested areas.

Just my thoughts.

Blank spaces...Your sample may have been weak
Unless you contact lab that did sampling the letters could mean anything.
Guy I know and I were trying to figure them out and how close pups were related to parents when we were getting ours DNA'ed.
When UKC switched labs it messed us all up because it changed their marker identifications.
Any way Lab would not tell him what area sequence represented due to liability issues.
Years ago there was the guy that was breeding Black and tans in Ok " F. Smith" that ran regular articles before DNA was even popular. How to understand them and showed his DNA results..

These letters could mean anything . Hair length, coat color,body size,,eye color, chop mouth, bawl mouth, etc.

Without getting to technical. Just trying to make this easy to under stand.
Lets say you have a stud dog with B/B over A/ A
You breed to a female with C/C over B/A
These two dogs depending on what this sequence and dominant or recessive gene traits they represent are totally unrelated and possibility of reproducing desired traits of sire or dam are way out there. Little to zero

I am over simplifying now but the double letters represent a more likely to be set trait and when bred to similar will reproduce more likely to replicate those traits.
To complicate matters a recessive gene can actually be a dominant trait. Such as the ticking in our Blueticks.
Okay Lets say this sequence we are dealing with represents a cherry color Redtick
Now lets say taking the same sire with B/B over A/ A and breed to a female with A/B over A/A. These two would be so closely related in traits in this case color cherry red ticking. you have the possible results in pups can only be
A/B over A/A or A/A over A/A . Odds are this whole litter should be cherry colored red ticks. This trait is so fixed.
Each parent will have contributed a letter to this trait but this is the only possible resulting combinations .

Lets say both parents had A/B over A/A and the top B represented a whiter back ground behind the cherry ticking.

Now we have possible B/B over A/A combination Which means we will now get some lighter colored pups with cherry ticking in this litter.

The other problem is these letters ARE NOT GENES. They are MARKERS, not genes so the same marker can be present on a gene that means two different things because of that. Let's say it is the 3rd position on the hair gene. Well that hair gene can be both long and short and still have the 3rd position so that letter will show up on both long haired and short haired dogs because it is just a marker, not a gene. It is a position on a gene.

The simple answer is there is nothing to understand about the DNA OTHER than it proves your dog is or isn't out of what its suppose to be. You can keep track of all the dna samples you want and you will never know what they point to.

Since we are unable to determine what these markers stand for you cannot say that a two capital letters(dominant) mean a dog is a better producer. Double letters being dominant for that trait will have more influence. These letters could stand for hair color, tail length, eye color, ear length whatever and may or may not have any influence on the dogs ability. They are simply a way to identify parentage. Sure a dog with double capital letters(AA) may be a good reproducer but just as many with combinations Aa and aa can be good reproducers too.

I was only trying to make it easier for him to understand the concept of the letters by "over simplifying " the lettering not the actual meaning.
And like you say a/a or A/A without knowing what they represent means nothing. Or whether they are a dominant reproducer .
Maybe it means they won't tree or prefers deer over coon.

I knew someone was going to say exactly what they did. I was actually hesitant to post because of that reason.
Don't wish to give out information that is incorrectly interpreted .
There is a lot more to it than can be written on this page. I already acknowledge there are numerous combinations per lettering and meaning. That is why I used all caps and same letters in descriptions .

I am in no way a authority on this subject.
Always say I know just enough to get in trouble.LOL.

DNA

I think they can or will soon be able to tell more about a dog by its DNA. Look at all the DNA websites for humans. They can tell everything from what region of the world your bloodline comes from. What medical issues 1 might be more likely have. They can even make a detailed picture of you, by only your DNA sample. So they can do all this with DNA but cant tell us anything about animals DNA... just my thoughts
