Let me get this straight....

[DUCKGIRL89]

Ok, so I have some orpington eggs in my incubator. And im trying to get the colors straight. (there are blacks, lavenders, blues, and splashes in the bator) and here is my question. . . . .

BlueXblue = 25% blacks, 25% splashes, and 50% blacks?

BlueXblack = 50% blue 50% black?

BlueXsplash = 50% blue 50% splash?

SplashXsplash = 100% splash?

BlackXblack = 100% black?

BlackXsplash = 100% blue?

LavenderXlavender = 100% lavender?

LavenderXblack = ??????

LavenderXsplash = ??????

LavenderXblue = ??????

Please let me know what I got wrong and right. And help me answer the other questions! Thank you!

for standard blue, Blue and blue make 25%black, 50% blue, 25% black. Black and black breed true, splash and splash breed true. Black and blue make 50/50, blue and splash make 50/50. Now if you had self-blue, that would be another story

Is that what black split or black/lavender split is, black with one lavender gene?

 

[fancyfowl4ever]

yea. Split means its visually one colour but also carrying another. lavender for example is only expressed visually when there are 2 genes present, so crossed with other colours you get splits that only carry one lav gene.

The bolded sections are not entirely correct. Lavender results from a bird that is Black and also carries two copies of the autosomal recessive Lavender gene. Thus, this is what happens:

Lavender (2 Black genes, 2 Lavender Genes) X Splash (2 Black genes, 2 Blue genes) = 100% Blue split to Lavender.
First parent gives 1 Black gene, 1 Lavender gene. Second parent gives 1 Black gene, 1 Blue gene. Offspring thus have 2 Black genes, 1 Lavender gene, 1 Blue gene. Appearance will be Blue, but genetically they will be split to Lavender.

Lavender (2 Black genes, 2 Lavender genes) X Blue (2 Black genes, 1 Blue gene) = 50% Blue split to Lavender, 50% Black split to Lavender.
First parent gives 1 Black gene, 1 Lavender gene.
Second parent gives EITHER:
1 Black gene and 1 Blue gene
OR
just 1 Black gene.
Thus 50% of the offspring will have 2 Black genes and 1 Lavender gene and appear Black, but genetically they will be split to Lavender.
The other 50% will have 2 Black genes, 1 Lavender gene, and 1 Blue gene and appear Blue, but genetically they will be split to Lavender.
