Genetics can be fun...

 I know, I know, you don't believe me. But take a look at this interactive budgie color calculator devised by a Hungarian enthusiast. If you click on "colorguide" at the top, you will be walked through, step by step, how to create a host of budgie color mutations,  starting with light green wild type clear through pieds, spangles, violets and even the sex-linked mutations such as cinnamon, opaline, ino, lacewing etc.

Thank you for sharing, it is fascinating.

I went to the Chelsea flower show the other day and there was such an array of unusual coloured dahlias. Tips of the petals in contrasting colours. It’s amazing what can be produced in the animal/nature world

Will have to have a good look when I’ve a bit more time. Thanks.

It's fascinating yellowfacedviolet, but I couldn't even work out which boxes to tick to work out what Billy and Iris chicks would look like

*note I am not going to let them breed!!

It's not so much a predictor of mating outcomes (since it doesn't account for splits, among other things) as it is a calculator of what makes up a particular budgie. That said, it could determine what some of the chicks would look like if produced by the hypothetical mating of Billy and Iris--just not all of them.

Billy = SF Yellowface Type II Mauve Spangle x Iris = Cinnamon Sky Clearflight Pied

Leaving unknown splits out of the conversation, the known mutations above would produce various combinations of:

100% Cobalts
50% SF Yellowface Type II
50% Spangles
50% Clearflight Pieds

So for example in a clutch of 4, you could have:

1 Cobalt Normal
1 Yellowface Cobalt Spangle
1 Cobalt Clearflight Pied
1 Yellowface Cobalt Spangle Clearflight Pied

There would be no cinnamons unless Billy is split to cinnamon. Barring that, Iris would pass a cinnamon gene on only to her sons and they would be split to cinnamon, not visual cinnamon.

😂😂 I was the same Marianne, I just thought it was me and didn't want to say 🤣

Thank you yellowfacedviolet that's interesting, they'd have a colourful clutch

jellybean, I'm never scared to look like an idiot

[jellybean]

When things are complicated I like to at least TRY and work them out, but this had me stumped.

I just don't get budgie genetics at all 🤔

That is fantastic! Thanks for sharing too.

However interesting is not the word I would necessarily use in this case to describe it, but it would definitely have "ing" on the end of it lol!!!
