Positioning Traits on Saga's Charts
Hi There Everyone,
I have been reading through some of the postings about where a trait is (proven) to be either dominant or recessive to another.
Many breeders think that just because a box shows one trait that it must be automatically hiding the other parents shown, and they (the breeders) then start telling everyone that's how it is. Then they get upset if another breeder says to them, that the first breeder's ideas could possibly not be right.
The hiddens in boxes can dictate a lot of things, for example:
Father is showing Tapestry Organica & hiding Odyssey Bellini
Mother is showing Fancie Purple Diamond & hiding Exotic Breeze
They have a box showing Odyssey Bellini
Now we all know that from Dominant to Recessive:
Fancie Purple Diamond
Tapestry Organica
Odyssey Bellini
Exotic Breeze
When some see that box they automatically think that Fancie Purple Diamond must be recessive to Odyssey Bellini cause that's what it looks like, but we know its not. The reason that the Odyssey Bellini is showing is that the hiddens go to war in the data base (that's how I like to say it....lol) and because the Exotic Breeze is the most recessive of the two hiddens it will hide under the Odyssey Bellini.
So you can see with this example that the hiddens dictated what would be showing, (well the database is doing the dictating) but either way it can steer breeders in the wrong direction.
Why I like the Saga charts so much is that they demand (to themselves) that they need at a minimum 2 or more exact proofs of where a trait is to end up on the charts. Some say this is a ridiculous way of doing it but it's the most sensible way of doing it. The Saga way absolutely proves the position of the traits as they are meticulous with the proofs behind each trait.
Wendi has started a series in the Saga newsletter ( [url=http://sagakitty.blogspot.ca/[/url] ) which shows how the Saga team determine a trait's position and I would suggest that all should read it so you have a clearer perception of why the traits are where they are on the charts.
I hope that this has cleared up a few things for those wishing to learn how traits are handled.
