** This thread discusses the Content article: Displaying your Dogs Pedigree on a Website. My Findings as a Webmaster **

This is a great article , full of brilliant information and I would like to thankyou for it I am of to check out the software you recomend

b

Are you going to sell the design?? says me hoping

Hi Betina
There really isn't anything to sell, all the software was free. The only thing I really created was the local database and I really am not a database person. When I get chance I can tidy it up, it's a bit of a work in progress and let you have a copy.

One thing I was thinking about was building up a pedigree database on this site. Members of the site could then 'embed' the pedigree charts in their own websites.

If you are looking at setting something up I'm happy to advise you if I can. Really the biggest problem is getting all the data in (and getting the data in the first place!).

Rob

Sounds a great idea. I know that you can acess 5 generation pedigrees on the Kilbourne site. I tried for Clunie and managed to get as far back as Prince Albert's Hector (1860's)on one line. But it is very tedious(but fun too)and once you are that far back you realise that most of the dogs come from the same few ancestors taht were recorded. An actual database would be excellent

Vicky

that's ll be a great idea
i've many dog in a database format gedlik I though I can check

most of them are from the UK

There is already a very good free database available online (other than the Peaches that is).
www.worldpedigrees.com/Default.aspx. Mike Herwin maintains the Deerhound database and you can find many many dogs in his database.

There is also an online database you can subscribe to, Mans Best Friend www.tbsxp.com/login.asp?E=1. This program provides much more than just the pedigrees-- it is a full management system. This company also has client-side software you can purchase, but I really like the idea of having an online version available and maintained vs a zillion personal databases.

What a great article. I'm currently on the same path but was hoping to get an extension or plug in for Joomla. Have you thought of using a chart creator? extensions.joomla.org/ext...ts/3687/details

Vicky

I didn't know about the google chart api. Looks iteresting, I'll have to have a better look into that, however from a quick glance it doesn't seem to do a pedigree chart layout. I did find these joomla extensions recently, although I've not tried them yet. I'm sure could be adapted for dogs...

Let me know how you get on though as this is still something I've got more than a passing interest in (although not a lot of time).

Thanks
Rob

How about adding what the % of inbreeding on the pedigree as well all Friesian horses have it on their pedigree and it is very useful

I'm developing software to calculate inbreeding coefficients from pedigrees. I've looked at Wrights method and the paths method. I've chosen the paths method but am getting strange results so I'm probably doing something incorrect in the calculation.

Does anyone have an in depth knowledge in this area, and if so can they kindly offer some advice as to where I'm going wrong.

Hi Robb
This is something that does interest me and I've often spoken about it to Elise (eyes glaze over picks up the paper etc etc). I'd quite a bit of research and found an excellent indepth explannation of the calculations involved, it was a bit of an eye opener to me. However, I can't find it now - typically.
Wikipedia has some general information...
en.wikipedia.org/wiki/Inbreeding
and I'll let you know as and when I find the article in question.
I've had a few thoughts about how the information could be displayed graphically, but its might be a case of reinventing the wheel...
I wonder if there are any isolated gene 'pockets' that have somehow remained outside majority - if you know what I mean..

Good luck

Rob

You've got me started now...
en.wikipedia.org/wiki/Coe...of_relationship
I wonder if we can fund a Phd...

Hi Rob,

Thanks for your interest. The problem that I have shows when I go back over more than about 9 generations. Less than that I get a low coefficient, more and I get a very high coefficient that is much higher than that calculated for both parents. It's probably a bug somewhere in the code, it does get rather complex, but I can't see where I'm going wrong!

What I really need to know is - Can inbreeding back say 9 generations have an effect of giving a dog a coefficient of say 20 times higher than it's parents? I would think not but this is new to me.

I've just got in a right mess trying to think this through what I want to say is that as you go back in the deerhounds past you have less and less information (is that true?) this means that it may look like the dogs are more inbred because the information doesn't exist. As a dogs coefficient is based on its parents coefficients what coefficient does a dog have if its actually coeffient cant be calculated (due to no knowing its parents) and could this be making your results look bad when you go back far enough for these unknown generations to have an effect?
Just a thought does it make sense?
Rob

Put simpler what coeffient are you giving a 'seed' dog? and could that have an effect on the results..

By Seed Dog do you mean the dogs in the oldest generation of the pedigree? These will assume a value of zero.

It came to me in a flash watching the dogs chase rabbits while out walking them. I've been including seed values for all dogs, not just those that are the seeds, therefore multiplying the coefficients by themselves many times over. The error only really manifests itself so badly after man generations.

Help would still be appreciated if anyone out there knows the inbreeding coefficient for any Deerhound. I could then check my result for that dog against it.

The further back you go the less the Deerhound population will have been, it was a real struggle for Miss Noble, and Miss Hartley to bring the breed through the war years, bearing in mind rationing etc

Also there are far more Deerhounds now than there were then, but I guess most today would go back to the few of yesteryear

Ok I am speaking out loud, time to go shut hens in , cuddle puppies maybe get some food for me for a change.

Rob I missed this post of yours and have only just noticed it.

It's true that the further that you go back the less information that you have, however the inbreeding coefficient also decreases over time, as its the chances of a dog inheriting a particular regressive gene from both parents it is effectively power(1/n) where n is the number of generations. Hence over say 12 generations it is 0.000244140625, for a particulat sire/dam combination, effectively a very small chance as over just 1 generation its a .5 chance and over 2 a .25 etc.

The actual inbreeding coefficient is the addition of all possible occurances of the same sires/dammes in a pedigree and these can add up to be quite high. My calculation seems to approach a limit after about 9 generations and I think that as I'm going back that far I do not need seed values in the dogs in the most distant generations of the pedigree.

I've calculated the value of my dog over 9 generations and it is 3.6% although over 5 generations with no seed values it's 0, after 7 generations just 1% and then quickly approaches the limit value of 3.6%
