The beginners key to sex-linked mutations
I probably spend a good two hours each week on average explaining sex-linked mutations. In general, sex-linked mutations are those that are linked to the X chromosome... To you & me, that's the Greek way of putting it. I explain it this way...
Sex-linked mutations, in general, consist of the following: ino (albino, lutino, creamino, rubino, etc) as well as cinnamon & opaline (pearl for most of us) BTW, in greencheeks, yellowsided is opaline. A male can be split for a sex-linked mutation, a female can not. If a female has the gene, she shows it, no ifs ands or butts. A female can not be split for any sex-linked mutation
If you have a male that is a sex-linked mutation, 100% of his female babies WILL be that mutation, but if he is split for that mutation, only 50% of his female babies will be that mutation. On the other hand, in order to have a male baby come out with
a sex-linked mutation, his mother MUST be that mutation AND his father must either BE that mutation OR be SPLIT for that mutation (split means the birds carries the gene, but does not show it)
A small sampling of sme sex-linked mutations below include pineapple (both cinnamon & opaline are sex linked, you can put a pineapple male with any female to get pineapple female babies) lutino (any ino will have red eyes, don't think that because it is yellow or white that it is lutino or albino, check the eyes). Pearl is a common one & most male pearl cockatiels lose their spots as they age but competition breeders are coming out with males that keep their spots. The last photo is of an opaline redrump hen and her cinnamon rubino male. both are sex-linked birds, the male gives me female babies that look just like him
