Green cheek conure mutations

[Tweetheart]

Hi, I’m really trying to wrap my head around mutations with very little success. I’m just going to ask a specific question. I have a turquoise male and a cinnamon/blue female. They had three babies. They look like 1 yellow side
1 cinnamon and 1 pineapple. Is this a possibility and could you tell the sex based on the visual colouring?

As far as I am aware you cannot sex conures based on color, I am not capable of answering the other questions though.

Actually, because you know the sex of the parents and there are sex linked mutations involved, you can tell some things.

So pineapple is really cinnamon yellow-sided. Both of these are sex linked genes.

Males need two copies of a sex linked gene in order to be visual, and they pass them on to both male and female offspring. They CAN be split.

Females only need one copy to be visual and they only pass the genes on to their male offspring. They CANNOT be split.

So if your female is not visual yellowsided (or visual pineapple since that’s a combo), then you know the gene for the YS came from the father. This means he must be split to yellow sided AND split to cinnamon.

So both of your babies with YS MUST be female because males require TWO copies to be visual and they didn’t get one from the mother.

The cinnamon baby could be either sex because the mother and father are both cinnamon. That one you should DNA sex.

All of the babies are split turquoise, as th father is turquoise and had to pass it on. Turquoise is recessive not sex linked so females CAN be split.

I had written this up a while ago and somehow didn’t actually add it to my site like I thought I did.

In my searching I found it very difficult to locate SIMPLE explanations of gene inheritance that didn’t make my eyes roll back in my head and require extensive visual aids to understand, so I wrote this up to help others who just want to get started with “how do I get color X, and what color will I get if I pair bird Y with bird Z?” And who aren’t used to dealing with words like “heterozygous” and “allele.” Yes these are important words but sometimes it help to have the stripped down function, how to get from point A to point B in your breeding program. You can always dig deeper but when I started out I felt like I had been thrown into the deep end. I hope this helps!
