You never know what your going to get, it's like a box of chocolates Unless you know the full history of the parents down the line you can't really know, it's a beautiful surprise

If you know the full genetics of your bird, you can use this fancy calculator to work out the expected offspring: www.gencalc.com/gen/eng_genc.php?sp=0BudgThe tricky part is that you very rarely know the full story, because many budgies are carrying multiple color mutations and they might not all be visible. Also, there are several mutations that look very similar, like lutino vs dark eyed clear or dilute vs greywing or yellowface vs goldenface. And certain genes are sex-linked, so the gender of the parent will have an impact on what genes are passed to the offspring. For example, a pure yellow budgie with red eyes is probably carrying the ino gene. Male parakeets have two Z chromosomes, while the females have one Z chromosome and one W chromosome. The lutino trait is caused by a gene carried on the Z chromosome, making this trait a sex-linked mutation. The same gene is responsible for albino (white) birds and lutino (yellow) birds. This gene effects pigment production required for the dark patterns (barring) and blue coloration, so only the base color shows through. On a normal green bird, the result is a solid yellow. The blue gene prevents yellow pigment formation, so any green areas will be blue and any yellow areas are white. Yellow is the base color for green budgies and white is the base color for blue budgies. An albino bird has both the ino gene and the blue gene. However, you will sometimes see yellow-faced birds with blue bodies. These birds have a different version of the blue gene which allows some yellow color in the head/face, but still prevents yellow in the body/wings/tail. Depending on the exact mutation, the result can be either be a bright yellow face and solid blue body or a yellow face with blue-green or teal body as the yellow pigment blends with the blue. Both blue and ino are recessive traits, so if you want to reliably reproduce these traits, you want both parents to be visibly displaying those traits. In other words, two inos will make more inos. Two blues will make more blues. But if you cross a lutino with a blue, you will probably end up with something completely different. The exact result will depend on the full genetics of both parents, since one of them might be split to blue or ino. But you are more likely to end up with a yellow base color non-ino bird (a normal green budgie with normal patterning). If you want blue offspring, then an albino or blue budgie would be a better choice rather than crossing to a lutino. If you desire ino offspring, you want to pair off with a bird who is visibly ino or a MALE bird with an ino parent, since he will carry the ino gene. Female budgies cannot carry a hidden ino gene, because the gene is sex-linked and they only get one copy. If they have the gene, you can see it. Here is a very nice article that goes over the many color mutations that are possible. puppiesareprozac.com/budgie-parakeet/colors-varieties-mutations-genetics/

Wow destinycall, budgie genetics are very complicated. My little Buddy had a dusty blue body with grey and white wing feathers and a yellow head. His dad was all yellow and his mom was the typical blue body and white head coloring.
