Therefore, brownish ("dirty") tints usually occur when the basic color pattern is bronze. In general, the grey (slate) does not replace the yellowish-brown or silvery-white of the basic plumage color. In areas where black is absent, the replacing color may be varying shades of yellow, reddish-tan, and brown or even silvery-white to white, depending on what other genes are affecting the color pattern. Up to this era, most grey (slate) turkeys shown were on a bronzeīase, which is essentially an arrangement of mostly brown and black pigments. it was noted that the basic color pattern of a given turkey modified the expression of grey (slate) in the plumage. As scientists studied the genetics of slate - Ghigi and Taibel in Italy (1929 & 1933), Walther, Hauschildt, & Prufer in Germany (1933), Jaap (1933) Marsden & Martin (1939), Jaap and Milby (1943), etc. Which approached "accepted" exhibition ideals tended to be heterozygous.īreeders at that time simply sorted poults by down and kept a select group for development and sold the rest. However, to complicate matters, complete dominance does not really occur in most turkey genes, and heterozygotes ( a single dose of a given gene) often create an effect somewhere in between, With slates we get an additive dilution effect with a homozygous slate ( carrying 2 doses) being much lighter than a heterozygote.įrom the time the Standard was written up through the 40's, turkeys Non-slate simply allows the black color to show inįull, normal intensity. The nature of the slate gene is to change black pigment in the feathers to grey (even though Standards prefer the more colorful terms of slatey-blue or even steel-blue).
Here's some additional info. on the history of the slate by Franklin Albertsen: Slate Poult Self Blue poult (aka Lavender) When breeding Black to Black, just Blacks result. When breeding Self Blue to Slate both Slates and Self Blues result, with no blacks. When breeding Slate to Black both slates and blacks result, with no self blues. When breeding Self Blue to Black, only slates result. When breeding Self Blue to Self Blue, only Self Blues result. When breeding Slate to Slate, the results are turkeys of three different colors, Slate,Self Blue and Black. Just want to make an important note here that most of the information found on some of the more popular websites on the results of breeding blue turkeys is inaccurate, the following is the correct results.
Mature weights: Toms 33 lbs, hens 18 lbs. The Black (Genotype:BBdd)is just that, black. The Self Blue "aka Lavender" is also black based but have two dominant slate genes.(Genotype:BBDD), they are more of a solid, dull, grayish-blue with the hens a lighter bluish gray. They are commonly called blue slate, sometimes called a Splash, their phenotype is slate or ashy blue with specks of black scattered over the feathers. First, I will try to define each color that occurs.Ī Slate, is black based with a single dominant slate gene. This variety is very interesting, and I will attempt to explain what can happen in breeding this color.
