Gouldian genetics question - need a reverse calculator?

[Jasmin]

Does anyone know if there is a reverse genetics calculator anywhere online where I might be able to plug in the colours of 4 Gouldian offspring so I know what their parents must be split to?
I'm very new with genetics and I'd like to solve the mystery!

or maybe someone on the forum can help me

Mom:
BH/PB/GB

Dad:
RH/PB/GB

Kids:

1. RH/WB/GB
2. YH or RH(straw colour)/PB/BB
3. YH or RH(straw colour)/PB/BB
4. YH/PB/GB

4 more not coloured yet, but all GB.

I just don't fully understand how those babies came out of those parents!

I can tell you one thing - if you have blue chicks then both Green parents are split to blue.

Wow - congratulations!!!

First you know that the male and female are split to White Breast for you to have a White Breast chick.
They also have to both be split to Blue to have a Blue chick.
They are also both split to Yellow Head to have a Yellow Head chick

I missed the WB chick completely - good catch, Debbie!

Mine isn't a calculator but I do have a reverse genetics article on my website:

Thank you very much

I wrote it down, and with the article, hopefully I can give myself a lesson in genetics!
