In green cheek conures, certain color mutations like cinnamon, opaline (yellowside), and cinnamon-opaline (pineapple) are s**-linked. This means that if a male carries these mutations, all the females that inherit the gene will visually display the mutation, while the males will be split for it.Turquoise is a par-blue mutation in parrots and is recessive, meaning either sex can be split for the gene. In this case, both males and females can carry the mutation without visually displaying it.
