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.
IT SEEMS THAT EVERYTIME A BREED OR LINE OF DOGS GET POPULAR IT EVENTUALLY LEADS TO ITS RUINATION BY UNINFORMED PEOPLE BREEDING WITHOUT DOING THEIR RESEARCH FIRST.
