Guinea Fowl Plumage Color Inheritance, With Particular Attention on the Dun Color

Plumage Color Allelism in the Red Jungle Fowl (Gallus Gallus) and Related Domestic Forms.

HE lack of an ancestral “standard of reference”, “normal” or “wild type” T for use in genetic studies of the domestic fowl has been of little concern to many poultry geneticists (for a recent discussion of this topic see JAAP and HOLLANDER 1954). In the field of plumage color inheritance, however, a standard of reference seems necessary in describing the action of mutant genes. What the standar...

Plumage color patterns of an extinct dinosaur.

For as long as dinosaurs have been known to exist, there has been speculation about their appearance. Fossil feathers can preserve the morphology of color-imparting melanosomes, which allow color patterns in feathered dinosaurs to be reconstructed. Here, we have mapped feather color patterns in a Late Jurassic basal paravian theropod dinosaur. Quantitative comparisons with melanosome shape and ...

Inheritance of Bulb Color in the Onion.

The Inheritance of Shank Color in Chickens.

Several publications in recent years have given conflicting reports upon the inheritance of shank color. Yellow shank color has been reported to be inherited in a simple Mendelian fashion, the sex-linked gene for yellow shank color ( U ) being dominant to its allele (y) , the gene for blue shank color. In contrast to this, the gene for yellow shank color has been reported to be autosomal, the r...

Attention-based color correction

This paper proposes a new algorithm that extracts color correction parameters from pairs of images and enables the perceived illumination of one image to be imposed on the other. The algorithm does not rely upon prior assumptions regarding illumination constancy and operates between images that can be significantly different in content. The work derives from related research on visual attention...
