The sex-linked red "Orange" locus, O/o, determines whether a cat will produce eumelanin. In cats with orange fur, phaeomelanin (red pigment) completely replaces eumelanin (black or brown pigment). [2] This gene is located on the X chromosome. The orange allele is O, and non-orange is o.
Meanwhile, another study led by developmental biologist Hiroyuki Sasaki at Kyushu University found the same genetic deletion in 24 cats in Japan as well as among 258 cat genomes across the world ...
The colors are often described as red and black, but the "red" patches can instead be orange, yellow, or cream, [2] and the "black" can instead be chocolate, gray, tabby, or blue.

The orange tabby, also commonly called red or ginger tabby, is a color-variant of the above patterns, having pheomelanin (O allele) instead of eumelanin (o allele). Though generally a mix of orange and white, the ratio between fur color varies, from a few orange spots on the back of a white cat to a completely orange coloring with no white at all.
A persistent joke about orange cats is that they all share a single brain cell among them. ... and their mom is a calico tabby. All of which is to say cat coat genetics can be extraordinarily ...
The homozygous form (MkMk) may be lethal as litter sizes are smaller than average. Unlike undersized cats of normal proportions (such as Toy and Teacup Persians), [6] dwarf cats suffer from a genetic mutation called pseudoachondroplasia (dwarfism without enlarged heads), a type of osteochondrodysplasia (bone and cartilage disorder). These ...
The orange tabby cat is also not a breed; instead, tabby cats have one of the most common coat patterns for both wild and domestic cats and are known for their striped coats. Cats.com shares this ...
