Therefore, a tortoiseshell cat may be a chocolate tortoiseshell or a blue/cream tortoiseshell or the like, based on the alleles for the (B) and (D) genes. [ 14 ] Female cats are homogametic (XX) and undergo the phenomenon of X-inactivation , [ 15 ] [ 16 ] in which one of the X chromosomes is turned off at random in each cell in very early ...
A cat which has both an orange and non-orange gene, Oo, and little to no white spotting, will present with a mottled blend of black/red and blue/cream, reminiscent of tortoiseshell material, and is called a tortoiseshell cat. An Oo cat with a large amount of white will have bigger, clearly defined patches of black/red and blue/cream, and is ...
The cat appears to be the famous two-faced cat, Venus, who is a popular social media fixture and is rumored to be a genetic chimera, a rare type of organism composed of two genetically distinct ...

A rare kitten was dropped off at an Oregon humane society, later stunning shelter workers when they realized how special he was. The kitten was discovered to be an intersex male tortoiseshell cat ...
Cat genetics describes the study of inheritance as it occurs in domestic cats. In feline husbandry, it can predict established traits ( phenotypes ) of the offspring of particular crosses. In medical genetics , cat models are occasionally used to discover the function of homologous human disease genes.
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 team called the gene variant w-sal, for salmiak — black licorice with a speckling of white salt. The researchers tested the salty colored cats and 178 normal-colored samples from the biobank ...
