cross table opaline


Opaline is the name of the melanin distribution in the plumage. The colour variety can have different colours. First developed is the rose opaline. is sex-linked. Only cocks can be split.
The best combinations are: cock 1 x hen 1, and cock 2 x hen 1. The first combination brings only opaline, cock 2 x hen 1. the second combination gives opaline cocks and hens and split cocks. The wildtype hen does not has the opaline factor.
Next best is the combination cock 1 x hen 2
There are combinations in which it is possible to get rid off the opaline factor, when we need pure wildtypes. For instance cock 2 x hen 1. Of course also in the combinations: cock 1 x hen 2, and cock 3 x hen 1.

(o) = opaline, ( /o) = split opaline, (-) = no mutation
