Gender specific inheritance

Tortoiseshell describes a coat coloring found almost exclusively in female cats. Also called Torties for short, they combine two colors other than white, either closely mixed or in large patches. The colors are often described as red and black, but “red“ can instead be orange, yellow, or cream and “black“ can instead be chocolate, grey, tabby, or blue. A tortoiseshell cat with the tabby pattern as one of its colors is a Torbie. “Tortoiseshell“ is typically reserved for cats with relatively small or no white markings. Those that are largely white with tortoiseshell patches are described as tricolor, tortoiseshell-and-white (in the United Kingdom), or calico (in Canada and the United States). Tortoiseshell markings appear in many different breeds as well as in non-purebred domestic cats. This pattern is especially preferred in the Japanese Bobtail breed. Tortoiseshell cats have coats with patches of various shades of red and black, as well as white. The size of the patches can vary from a fine speckled pattern to large areas of color. Typically, the more white a cat has, the more solid the patches of color. Dilution genes may modify the coloring, lightening the fur to a mix of cream and blue, lilac or markings on tortoiseshell cats are usually asymmetrical. Occasionally tabby patterns of black and brown (eumelanistic) and red (phaeomelanistic) colors are also seen. These patched tabbies are often called tortie-tabby, torbie or, with large white areas, caliby. Tortoiseshell can also be expressed in the point pattern. Frequently there will be a “split face“ pattern with black on one side of the face and orange on the other, with the dividing line running down the bridge of the nose. #protein #AminoAcids #gene #Heterozygous #nucleicAcids #explainEverything #geneticDrift #geneticInformation #tRNA #enzyme #Inbreeding #autosomal #Nucleotide #genotype #NaturalSelection #Haploid #metaphase #nucleicAcid #gametes #Breeding #doubleStrandedDNA #genotypes #genetic #cytosine #genes #TumorCells #GeneticsLecture #chromatid #Primers #AllelicFrequencies #cytoplasm #lawOfProbability #ExplainEverything #punnettSquare #recessive #DaughterCells #dominant #mRNA #inheritance
