In fact, the calico coloring happens only by accident due to genetics. Compared to a normal tomcat, his spraying and his sexual behaviour were half-hearted. Could a black embryo and a blue embryo (either or both having white spotting) have fused just after fertilisation and then split into 4 parts, each of which has developed into a chimeric kitten? A dilute calico has the same white base, but their patches are softened to charcoal gray, cream and light orange. In the rare instance of a male calico kitten being born, there is a 1 in 3,000 chance of it being sterile due to an abnormality in a male calico’s genes, which causes him to have an extra X chromosome. A chimera is an organism with two sets of DNA. It wold take some experimental matings to work out what is happening. Research during the twenty-first century suggests that chimerism is a more common cause of tortie males than the XXY chromosome abnormality. Some of those cells may slip from the mother's bloodstream into the body of the next child. BJ Andersen, Executive Director of Willamette Humane Society provided these photos of Ariel and Bridgette who appear to be chimera twins. It would require tissue tests to confirmed that Venus was a chimera ("fraternal twins in a single body"), because such colouration occurs as a striking manifestation of normal tortoiseshell genetics. Bred to the tortie point Who’s Your Daddy (Hoosier), he sired 5 kittens, 2 of which were flame point Himalayan females. Ultimate TomoNews Compilations - Can't get enough of TomoNews?

Blue-eyed ginger cats are unusual, but not unknown and may be related to the white-spotting gene. It is not known how common tetragametic chimerism is in the population since there are often no outward signs, especially where same sex embryos have fused (a few might have visible pigmentation mosaicism). Nature reported a similar case in 1979, when genetic tests suggested that a woman could not be the mother of any of her four children. In mammals, chimeras are usually only identified when there is a mismatch between the chromosomal sex (XX or XY) and the genitalia. The chimera effect can occur on the cat’s entire body or on just its face. It is hoped that he can be test-mated to a blue-point Ragdoll later on to see which of his two colours he passes on. You will not get bored around them, and their stunning colors are pleasing to watch. - Dr Chris Helps, Senior Research Fellow, Head of Molecular Diagnostic Unit, University of Bristol, Langford Veterinary Services, Bristol.

Roshelle describes it as "when she is sitting, from the side, it almost looks like she has a long gown with a hoop skirt under it, and layers of lace (brindling), on the dress!". The colour of the fur is linked to eye colour, so a mutation in that area could affect both skin pigment and eye pigment. He only has male sexual organs, coming from the male flame point embryo. Both have similar distribution of the red tabby and lilac colours. DNA tests confirmed in 2018 that Narnia is not a chimera. To have a mosaic pattern of both black and cream, she would have to be a chimera of a black (non-dilute) embryo and a cream (dilute) embryo. Chimeric cattle are not at all rare. This can come about through investigation of an illness or through visual clues such as tortoiseshell coats in male cats. One of the species that most frequently forms chimeras in nature is cats.

Skipper's attitude to females was very different. Although his condition was assumed to be due to an extra X chromosome (XXY, Klinefelter Syndrome), this does not normally result in female behaviour in phenotypical male. By the time he was almost 2 years old, he still did not spray and still showed no interest in mating with females. This mix of dilute and non-dilute can occur due chimerism or to "mitotic non-disjunction."

The different cell lines can give rise to different fur types as well as different fur colours. Another human chimera apparently occurred when an unfertilised egg divided into two.
