![]() ![]() Regardless, Manny will live a long and happy life. We would need to do further testing called karyotyping to find out what which type Manny is. For example, one zygote had a black coat color and the other an orange. Zygotes are formed just after fusion of the egg and sperm. Chimera: This is where two zygotes fuse together.For example, the original X coded for black coat color and the mutation coded for orange coat color. In the case of coat color, the mutation would be in the skin cells. Somatic Mutation: This mutation in the somatic (non-germinal (sperm or egg)) cells in the developing embryo.The Y codes for male genitalia, one X codes for black coat color and the other X codes for orange. XXY Male: (known as Klinefelter’s Syndrome in humans).There are three ways that this can happen: How can Manny’s coat have black, orange and white since he would need to be genetically XX in order to have both orange and black coat colors? We know XX equals female genitalia so how can Manny be male? The white color is coded separately on a non-sex chromosome. ![]() Males only have one X, so they can be solid black or orange but not both. This is because calico cats have a genetic condition called piebalding. What is the difference between a tortoiseshell and calico Calicos differ from tortoiseshell cats because they have patches of white as well as patches of orange and black. Since female cats have two X chromosomes, they can be solid black, solid orange or both black and orange. Tortoiseshell cat (Source: Lucashawranke CC BY-SA 4.0 via Wikimedia Commons). The X chromosome codes for the coat colors – orange/red and black. There are different genes that come in to play to determine the pattern of stripes or spots and how they are expressed in a given cat.Ĭats’ coat colors are linked to their sex chromosomes (XY). Calico and Tortoiseshell cats can also have tabby marks within the colors – this is known as a ‘patched tabby’ pattern sometimes also referred to as Torbie or Tortoiseshell Tabby. However we can generally see the stripes in a lighter color (orange) but they may be hidden in a darker color (black). The stripes that we see on a cat’s coat are also related to the pattern, but not specifically the color. Tortoiseshell cats have mottled orange and black colors usually with little or no white. Calico coats have large patches of orange, black and white.
