First, on getting your bird a mate, PLEASE READ THIS. If you care about your bird, don't ignore this article. It barely scratches the surface of breeding issues. The second part has more to do with you than the first.

Ok, pineapple is a combination of two "sex linked mutations; cinnamon and yellow sided. In sex linked inheritance, the female only has one location for the gene, so she can only carry one copy and only needs one copy to show that she has it. We refer to this as being "visual" cinnamon, meaning the gene is not being carried without showing. A male has two locations, can carry two copies, and needs two copies to be "visual" cinnamon, etc. if he has only one copy, he will hide the gene, that is, he will be "split" to that gene.
So when making babies, if the male is visual pineapple, his daughters will be visual pineapple. If the female is visual pineapple, her sons will be Split to pineapple, but not show it unless the male also carries the cinnamon and yellow sided genes which make pineapple.
Turquoise is recessive, not sex linked. This means both parents can carry either one or two copies and pass them along. If the baby receives two copies, he will be turquoise, one copy will make him carry the gene but not show it.
So, if your bird is male, carries no splits, and you get a female turquoise who also carries no splits, you will get visual pineapple females split to turquoise and visual normal green males split to pineapple and turquoise.
If your bird is female and carries no splits, and you get a male turquoise who carries no splits, all the babies will all be visual normal greens split to turquoise and the males will be split to pineapple.
