The situation with cocks is slightly different, in that the sex-linked mutation can appear in both visual form and in split form. With sex-linked forms, if the mutation is present in hens, then it must appear visually a hen cannot be split for a sex-linked mutation.
Therefore it follows that cream cannot be carried in hidden form (normally referred to as split) in either sex. In an earlier article on breeding dominant mutations, it was pointed out that if the mutation was present, both cock and hen would visually show the characteristics of that mutation so (for example) a dominant dilute cock in the fawn series would be visually cream.

There are some simple ground rules to understanding how to reproduce these mutations. Pairings to Produce Sex-linked Mutation Zebra Finches For zebra finches, there are three such mutations commonly available namely, fawn, lightback, and chestnut flanked white. In the case of birds, cinnamon canaries, opaline, cinnamon, and ino budgerigars are all examples of sex-linked mutations. However, sex-linked mutations occur in many varieties of birds, and some mammals. Many beginners shy away from the term sex-linked inheritance because they believe that it must be complicated.
