Whats the deference between Gouldians and Dilute Gouldians?

Dilute is a combining of the yellow (z) and green (z) chromosomes in a bird that has a purple chest (both the green and yellow chromosomes are sex linked) If you see a dilute you can be sure its a cock as hens cannot be dilutes.
Visually the dilute is a lighter shade because each of the green and yellow chromosomes are trying to express their colour but as neither can be fully expressed the colour of the bird is neither yellow nor green.

there are lots of mutation pics on there. It might be worth having a look at the genetic forecaster too

you can play with loads of colour combination's to see what colour pairings would produce what colour chicks.

Bet you are glad you asked.....
