Blue gouldian breeders

I am aware pastel DF is a silver caring the yellow gene only, but the pastel (SF) (cock) carries the green and the yellow gene, when put into breeding program paired to a split green back hen produces 8 outcomes of 12.5% each, offspring being green, yellow, dilute, pastel, blue and silver off spring

Correct,the green off spring are split blue,the yellow off spring are split blue as is the single factor hens (don't use the word dilute)you should not produce SF cocks as EY is sex linked dominant so pastel is SFYB blue cock which should not happen.
Blue will happen as will SFYB blue hens called silvers if that makes sense from that pairing of SF pastel blue cock and a split blue green back hen. Cheers Craig

I think my head is ready to explode,I understand none of this.

You have only mention 6 out comes not 8, what are the other 2?
Just stiring the pot guys taking advantage of a typo...

I love Gouldian genetics, always learning..
