If a white cat and a white cat, what will the kittens be like? - briefly
When two white cats mate, the color of their kittens can vary. The kittens may be white, but they could also exhibit different colors, depending on the genetic makeup of the parents.

Understanding the genetic inheritance of coat color in cats involves delving into the principles of genetics, particularly focusing on the genes that determine white fur. When two white cats mate, the resulting kittens' coat color can vary due to the complexity of feline genetics. This variation is influenced by several factors, including the specific genes responsible for the white coat and the genetic background of the parent cats.
The white coat in cats can be the result of different genetic mechanisms. One of the most common is the presence of the dominant white gene (W), which is responsible for the complete absence of pigment in the fur. This gene can mask the underlying coat color and pattern, making the cat appear entirely white. However, the dominant white gene does not affect the eyes or skin, which may still exhibit the original color or pattern.
Another mechanism for white fur is the presence of the white spotting gene (S), which can result in varying degrees of white patches on the coat. This gene is recessive and can produce a range of white patterns, from a few white spots to a completely white coat. The white spotting gene can also affect the eyes and skin, often resulting in blue eyes or depigmented skin patches.
When two white cats mate, the genetic makeup of their kittens will depend on the specific genes responsible for their white coats. If both parents carry the dominant white gene (W), the kittens will likely be white, as this gene is dominant and will mask any other coat color or pattern. However, if the parents carry the white spotting gene (S), the kittens may exhibit a range of white patterns, including completely white, partially white, or no white at all, depending on the genetic combination they inherit.
It is also important to consider the potential for hidden genes in the parent cats. Even if both parents are white, they may carry recessive genes for other coat colors or patterns. These hidden genes can surface in the kittens, resulting in a variety of coat colors and patterns. For example, if both parents carry the recessive gene for black fur (bb), there is a chance that some of the kittens will be black, even though the parents are white.
In summary, the coat color of kittens born to two white cats can vary significantly due to the complex interplay of genetic factors. The dominant white gene (W) and the white spotting gene (S) are primary determinants of white fur in cats, but other hidden genes can also influence the outcome. Understanding these genetic principles can help in predicting the potential coat colors and patterns of the kittens, although the actual results can still be influenced by the unique genetic combinations inherited by each kitten.
