Cross-table 63: Edged-pastel, recessive and recessive

1. First year: We combine an edged cock and a pastel hen. The reason that we use an edged cock and not a hen is because there are much more strong edged cocks then hens. We use a yellow edged, without a red suffusion on the back and wings. Result: We breed only wildtypes, cocks and hens. Both are double splits.

2. Second year: We combine both double splits wildtype. It is possible to breed the edged-pastel, but the percentage is very low. The wildtypes are not useful any more because we cannot find the real double splits. We can use in principle all the edged and the pastels and of course the edged-pastels. But we choose only the edged cocks and hens, and the combinations edged-pastel, if we got them to mate in the next year.

3. Third year: We use the edged-pastels and the edged, both cocks and hens. We choose the best edged we can get, edged with only a little bit of eumelanin left in the tips of the feathers. Of course this is the ideal situation. May be we have to lower our ambitions. The edged is not an easy mutation. The variation is very big. But if we have luck we are breeding in the third year enough edged-pastel combinations. The yellow pigment of the yellow pastel combined with the yellow pigment in the edged gives a deep bright yellow.
When we want to breed the yellow edged-pastel with a red suffusion, we need to use the red pastel in stead of the yellow pastel, we can use the same cross-table.
The full cross-table of all the possible edged, pastel and wildtypes is not interesting while the inheritance of the edged mutation is not fully clear. So mating of the pastel, split edged (p/e), wildtype (/e/p), edged (e), pastel (p), split edged (/e) and split pastel (/p) is not interesting for our goal: edged-pastel, it cost to much time and the result is problematic. Much less edged are born then we expect.

Abbreviations:
(e+p) = edged-pastel combination.
( /e/p) = wildtype split edged, split pastel
( e/p) = edged split pastel

( p/e) = pastel, split edged
( /e) = split edged
( /p) = split pastel
(-) = wildtype, no mutation factors
