Excerpt from Studies on Inheritance in Poultry: The Factor for Black Pigmentation in the White Leghorn BreedBefore presenting the experimental results, a word should be said regarding the zygotic constitution of the White Leghorn, since this point has an important bearing upon the interpretation of any results Obtained. This breed is characterized by the so-called dominant white, as contrasted with the recessive white present in the majority of other white breeds, including the White Plymouth Rock, White Minorca, and White Silky, for example. In crosses between the White Leghorn and such black fowl as Black Hamburg, Black Minorca, Black Spanish and Black Java, the F1 birds are invariably White, frequently Showing splashes or ¿ecks of black, and less Often a barred or partly barred feather. In F 2 the typical Mendelian ratio appears, 3 white 1 dark. The dark birds comprise both black and barred individuals in the ratio 1 3, as stated in an earlier paper.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
