APBT vs Amstaff DNA ??

Quick question for an article I am writing.
If the APBT was used to establish the AKC breed standard for Amstaffs & the first Amstaffs were Colby dogs, how come DNA testing crowds like "EmbarkDNA" claim they can differentiate between the APBT, SBT & AST ?
Are they legit ???

 

I reckon dna testing to figure out the ancestry of all the various dog breeds to be about as valuable as fools gold.... I suspect after the cheque as been cleared they will cheat a lil bit by telling you of the likely culprits (based on historical writings) and add one or two outside exotics just to make you feel like it was money well spent...lol

Essential it's the same question as "what came first, the chicken or the egg....dunno but they both taste nice with a pitch of salt.

 

....their genetic makeup are bound to weave in and out amongst each other, just some moreso or less so

 

opps I forgot to mention I've got a PHD in bullshit...lol

 

The dna testing was done sixty years apart lol.

if you would of dna tested a colby dog and one of the first registard amstaffs the the dna would of been the same.
but if you do that now you got dna whats sixty years apart.
