How to Use the Tables
Behind some of the crossings, percentages are presented: 100%, 50%, 25% and 33 1/3 %. Other percentages, however, are not given, as in such matters complicated theories must first be explained, such as crossing over type I and II. And because those percentages have no meaning for our tables-the correct results are only given behind the most important crossings-we will not go into these technical and often very complicated matters. In Table 1, for instance, you will find the crossing: dark green/white x light green/white; in other words: a crossing of two birds the first of which is dark green in external appearance (phenotype); the second bird light green; both however are split for the color white (or: carrying white as a recessive color). As all the given crossings in the tables are based on a percentage of 100 birds, it should be understood that this crossing only presents the possibility of obtaining a light green Budgie. But, also understandably, not for 100%, as you have a chance of getting young birds of the following colors as well:
1. dark green 2. light green/blue 3. dark green/blue 4. light green/yellow 5. dark green/yellow 6. light green/white 7. dark green/white 8. light yellow 9. dark yellow 10. light yellow/white 11. dark yellow/white 12. skyblue 13. cobalt 14. skyblue/white 15. cobalt/white 16. white/blue 17. white cobalt
Hence: together with the light green bird, eighteen (18) possibilities exist altogether. The following crossing: dark green/white x dark green/ white; gives no less than 27 possibilities, as, besides the 18 just given.
19. olive green 20. olive green/blue 21. olive green/yellow 22. olive green/white 23. olive yellow 24. olive yellow/white 25. mauve 26. mauve/white 27. white/mauveThe crossings with the given percentages present the quickest way to obtain the desired colors. From Table 3, for instance, it becomes obvious that all the young from light green x skyblue are for 100% light green/blue; the same applies when we pair a male skyblue with a light green hen. The second crossing of Table 3 is light green x cobalt; the outcome is 50% light green/ blue, and 50% dark green/ blue. The crossing dark green x light green/ yellow on the other hand presents only 25% dark green/yellow, and further 25% light green, 25% light green/yellow, and 25% dark green/yellow. A sample of crossing dark green x cobalt. Stated is that 33 1/3 % of this crossing will present dark green/ blue; the other possibilities are light green/blue, and olive green/blue, each, of course, for 33 1/3%.
YOU CAN USE THESE TABLES IN A DIFFERENT WAY AS WELL!
You have, for example, a pair of Budgerigars, one of which is light green, the other dark yellow. By checking ALL CROSSINGS light green x dark yellow in the tables you are able to find the outcome, as each table deals with only one given color. From the above crossing you may expect: 50% light green/yellow, and 50% dark green/yellow. A crossing of cobalt x light green/white will present the following possibilities: 1. light green/blue 2. dark green/blue.
Crossing dark yellow x dark yellow/white gives the following possibilities:
1. light yellow 2. dark yellow 3. olive yellow 4. light yellow/white 5. olive yellow/white
