Data Validation: Historic Chinook Sireline(s)

[Karen Hinchy]

Hi all,

There's been (surprisingly) little discussion on the proposal to update the pedigrees of the dogs for which we have contradictory DNA evidence in the CPP data.  This will not impact AKC/UKC registration, although I will notify the parent clubs of the final outcome of the CPP agreement if it contradicts their current pedigree data.  

So, I've restated the proposal below.  If you disagree with this proposal, please object by noon EDT Sunday 29 April and we can continue discussion and/or move to a vote.  

• North Wind dogs (both litters) - OPEN full pedigree based on DNA noting there cannot be single sire and disputed DNA evidence there is not a single dam. 
  
• Benjamins (SW Nanook x Yokayo Cheena litter) & Georgianna's litter:  OPEN sire side of pedigree.
  

It should be noted that this action will artificially drop the COIs of every single Chinook.  Some pedigrees will only be complete through 4 generations, most through 5 or 6.  Breeders are cautioned to consider genetic testing to determine homozygosity, or use strict guildelines for 5 gen COI (e.g., < 5%).

Excellent. Well stated. Agreed.

Good Notes & Cautions too, imho, Karen.


And just FYI, I already Updated Ahna's PED in my dbase & Uploaded it again to her continued MARS OS profile too. So active breeders can/will see what that continues look like as compared to her OS GENOTYPE itself.
(Her likely false low 10G COI indeed dropped to a further false low by roughly 32% even, yes. But me too- NOT paying much attention right now to the 10G dbase COIs, LEAST of my concerns this hour! SINCE we have the new REAL INDIVIDUAL real diversity genotype(s), exactly!)

I also Updated Lander's new Embark Profile image this morn, to simply be COPY of his COA Reg Cert, in honor of his being sole remaining SWC Molly kid here which ran under prior COA CB program. After also having REMOVED G Boney's (& Sheena's) SIRE within my dbase too. So my dbase is effectively updated in retrospect again then. Steady as we go.

All's good by me, to date, therefore. best, seb

Even without the artificial lower COI with open dogs, it is easy to fall into the trap of believing that Chinooks without common ancestors in 4-5 generations are diverse from each other.  This was really cemented to me when I received Mouse's OS testing back and the diversity rating for males that I would have thought would be good matches based on pedigree were not good matches at all.  Then there were males I would not have considered, thinking they were too close, that actually were more diverse.

Well, it’s true, Carie that some dogs end up being better genetic matches than you’d think based on pedigree. Largely because they are all so closely related that random inheritance plays a bigger role.

"Largely

inheritance plays a bigger role."

Which Role will continue grow, until we broaden the remaining Ref Pop. Or Extinct. Choice remains ours, witting or non.

But I too sure hope many will 'do nothing' so's to live to be the last owner of the 'last(s)' Stud & Dam(s) standing, frankly. For that remains most inhumane means of extinction(s). And yet it IS the means by which MANY also REAL AKC/CKC studbooks have ended/extincted, agreed.

And that should have read a double negative: I hope many will NOT 'do nothing', ...

Otherwise, I'm all done ranting in 2018. The choice is clearer than ever both whether to act, and HOW. Thank you again to also COA/UKC CBCP, as well as CPP, MARS OS, Embark. best, seb

Susan I’ve been meaning to ask, do you still have Chinnoks

[Susan E Bragg]

12 Chinooks still, 0 Chinnoks (grin ;).  best, seb

Your lucky, I’m down to one, two months ago I had to put Tobin down.  I remember driving up to North Dakota with Carie to pick up two of your dogs, Sparkle and TB.  Sparkle was a wonderful dog much loved by Carie and the Chinook community in the Pacific Northwest.

[Susan E Bragg]

Sorry for your loss of Tobin. :(
3 of our remaining 12 are also Sparkle offspring, so her bright soul remains strongly felt here too. But/and all 12 are already well within their 'clinical' 'geriatric' years here. So your memories of 8yrs ago remain both like yesterday as well as light years since, sad but true.

We still miss Spark & TB too, just 1 each of their full sibs left here already. My greatest luck this year is to have more borrowed time with both of them as well as elder Lander, who may yet see his 16th birthday come September, if Summer is kind to us! Otherwise; Time wait(s) for no (wo)man or dog indeed. (Nor their genome, when it's as narrow as this one remains circa 2018.)

Dear Marleen,

I'm saddened to hear of Tobin's passing. He was such a lovely Chinook with a big heart.

[Karen Hinchy]

Just a bit of house cleaning- 

There were no objections to this proposal to update the pedigrees of the North Wind, Benjamins, and Georgianna's dogs.  So I have made the relevant modifications to the CPP data.  I will also notify the CCA and COA in the event they wish to modify the historical pedigrees with AKC or UKC.  

The updated file is at: https://docs.google.com/spreadsheets/d/11iNCzakU7vWTwyrRAIaHYWtVGSd9Q2K299YjYeakeek/edit#gid=1565790843

[Susan E Bragg]

Excellent, on all accounts/points/works, thank you.
Downloaded file already.
