Step-by-step instructions for the first-time user Retour Accueil  

If you wish to compute the possible colours out of a given mating, you must fill the breed/colour description of the potential sire (number 2, on a blue background) and of the potential dam (number 3, on a pink background). You may also wish to enter more details on their ancestors by filling their description like on a pedigree.

Here you will find step-by-step instructions on how to proceed through an example.
We would like to know what colour could be the offspring of Roller de la Chacolaterie, a lilac silver male somali, with Vivacia de Buffavand, a sorrel female somali.

In this program, a cat's phenotype (its appearance, here breed and colour) may be entered by one of two methods:

- either the cat is already registered on the E.R.o'S. database, and the first method may be used. It is a very quick method because only the E.R.o'S. number of the cat must be typed, and the whole pedigree of this cat will be filled automatically.

- or the cat is not already registered on E.R.o'S., and therefore the second method must be applied.

 

I know that Roller de la Chacolaterie is registered on the E.R.o'S. database under number 228264,
so I type "228264" in the second field of the box for cat number 2
(do not type it in the first field, which is for the cat's name)



then I click on to confirm my choice.
The program will fetch automatically the data for Roller and his ancestors,
and fill the corresponding pedigree boxes.

Then I fill in the queen's E.R.o'S number, in the second field of the box for cat number 3,
since I know that Vivacia's E.R.o'S. number is 507262.



Having typed in 507262, I click on to confirm and let the program fill in the rest of the data:

Well, the pedigree of the future parents looks good now !
What remains to be done is click on to get the result:

pedigree : OK

Potential (LOOF recognised) offspring of cats : somali lilac silver(2) x somali sorrel(3)

- somali chocolate
- somali chocolate silver
- somali lilac
- somali lilac silver
- somali sorrel
- somali sorrel silver
- somali fawn
- somali fawn silver

 

I must enter manually the fact that Roller is a lilac silver somali.
I go to the box of the stud (cat number 2) and click on the lift of the third field to choose the breed.
I then click on "somali" among the choices offered.



then I click on to confirm my breed choice and proceed with the colour choice within this breed..



I click on the lift to choose lilac silver as a colour, then on to validate my colour choice..



Since I'm finished with the possible choices, the button which was before appearing as now appears as (correction),
and I will not have to use it unless I want to start again with the breed/colour selection of cat number 2.

If I wish, I can also additionally type in the cat's name in the first field of the box for cat 2.
This is only to improve legibility of the pedigree for me, but will not have any impact on the program's result.



 

Now I am ready to proceed in a similar way for the future queen (cat 3) who is a sorrel somali:

I click on the lift in the third field of box for cat number 3, I choose "somali" as a breed,
then I click on to confirm my choice and proceed with the next step,
then again on the lift to see the choice of colours, where I choose "sorrel",
then again on to validate my choice of breed/colour.

If I wish, I may optionally type in "Vivacia" in the first field of the box for cat number 3.



Now, I may wish to give more information to the program as to the breed/colour of the grand-parents,
great-grand-parents, etc., i.e. the ancestors of Roller and of Vivacia.
To do so, I proceed in the same way as explained above for cats 2 and 3, but in boxes for cats 4, 5, 6, 7, 8, etc.

You may want to do it as an exercise.

For my example here, let's stop there and click on the button
to get the possible breed/colours out of the mating of a lilac silver somali stud with a sorrel somali queen:

pedigree : OK

Potential (LOOF recognised) offspring of cats : somali lilac silver(2) x somali sorrel(3)

- somali chocolate (if the sire is a carrier of non silver (locus I) )
- somali chocolate silver
- somali lilac (if the sire is a carrier of non silver (locus I) ) (if the dam is a carrier of dilute (locus D) )
- somali lilac silver (if the dam is a carrier of dilute (locus D) )
- somali sorrel (if the sire is a carrier of cinnamon (locus B) and non silver (locus I) )
- somali sorrel silver (if the sire is a carrier of cinnamon (locus B) )
- somali fawn (if the sire is a carrier of cinnamon (locus B) and non silver (locus I) ) (if the dam is a carrier of dilute (locus D) )
- somali fawn silver (if the sire is a carrier of cinnamon (locus B) ) (if the dam is a carrier of dilute (locus D) )

Note: these results give conditions (like "if the sire is a carrier of ..."),
which did not appear in the first method. This is because here I have not filled the data on the ancestors,
which in this particular example would have given the clue as to whether these conditions are fulfilled or not.
For instance, knowing that Roller's mom is a chocolate somali proves that Roller is definitely a carrier of non-silver,
and knowing that his dad is a fawn silver somali proves that Roller is a carrier of cinnamon.
Similarly, knowing that Vivacia's mom is a fawn somali, we know that Vivacia carries dilute.
