If a white cat mates with a red cat, what color will their kittens be? - briefly
The color of kittens resulting from a mating between a white cat and a red cat can vary. Typically, the kittens may exhibit a mix of these colors, often resulting in cream, tortoiseshell, or calico patterns, depending on the genetic traits inherited from each parent.

When considering the potential coat colors of kittens resulting from a pairing between a white cat and a red cat, it is essential to understand the genetic principles governing feline coat coloration. This involves examining the inheritance patterns of the genes responsible for these colors.
Firstly, it is crucial to recognize that the white coat in cats can be due to several genetic mechanisms. One common cause is the presence of the dominant white gene (W), which can mask underlying coat colors. This gene is not associated with any specific coat color but rather overrides the expression of other color genes, resulting in a completely white coat. Another mechanism is the presence of the piebald gene, which results in white spotting on the coat.
The red coat color in cats is determined by the presence of the orange gene (O), which is located on the X chromosome. This gene is responsible for the production of pheomelanin, the pigment that gives the coat its red hue. Since the orange gene is sex-linked, its inheritance can differ between male and female cats. Female cats have two X chromosomes, so they can be homozygous (O/O) or heterozygous (O/o) for the orange gene. Male cats, having only one X chromosome, can either have the orange gene (O) or not (o).
When a white cat and a red cat mate, the resulting kitten colors depend on the specific genetic makeup of the parents. If the white coat is due to the dominant white gene (W), the kittens may inherit the white gene and appear white, regardless of the other color genes present. However, if the white coat is due to piebald spotting, the kittens may exhibit a mix of white and red patches, as the piebald gene allows for the expression of other coat colors in the areas not covered by white spotting.
For male kittens, the inheritance of the red coat color is straightforward. If the father is red (O) and the mother carries the red gene (O or o), the male kittens will have a 50% chance of inheriting the red gene and thus being red. If the father is not red (o), the male kittens will not be red, regardless of the mother's genetic makeup.
For female kittens, the inheritance is more complex due to the presence of two X chromosomes. If the father is red (O) and the mother carries the red gene (O or o), the female kittens will have a 50% chance of inheriting the red gene from the father and a 50% chance of inheriting it from the mother. Therefore, the probability of a female kitten being red depends on the combination of genes inherited from both parents.
In summary, the coat colors of kittens resulting from a white and a red cat can vary significantly based on the genetic mechanisms underlying the white coat and the inheritance patterns of the red gene. White kittens may result from the dominant white gene, while red and white kittens may exhibit piebald spotting. Male kittens have a straightforward inheritance pattern for the red gene, while female kittens' coat colors depend on the combination of genes inherited from both parents. Understanding these genetic principles is essential for accurately predicting the potential coat colors of the offspring.
