If a white cat and a white cat have kittens, what will they be like? - briefly
If two white cats mate, their offspring could potentially exhibit various coat colors depending on the genetic makeup of both parents. The primary factor influencing the kittens' appearance is the presence or absence of specific genes that control fur color and pattern.

The color of a cat's coat is determined by several genetic factors, primarily the presence or absence of certain pigments. When it comes to the offspring of two white cats, the outcome can vary depending on the underlying genetics of each parent.
Firstly, let's consider the possibility that both parents are true albino cats. Albino cats lack melanin, a pigment responsible for coat color and eye color. If both parents are indeed albinos, all their kittens will also be albinos, exhibiting white fur and red or pink eyes due to the absence of melanin.
However, it is important to note that not all white cats are albino. Some white cats may have a different genetic makeup, such as being heterozygous for coat color genes. In these cases, the kittens could inherit various combinations of genes, leading to a range of possible outcomes. For instance, if one or both parents carry recessive genes for other colors, some of the kittens might not be white but instead exhibit those recessive colors.
Additionally, the sex-linked nature of coat color in cats plays a significant role. The gene responsible for orange fur is located on the X chromosome. Female cats have two X chromosomes and can express this gene more readily, while male cats only have one X chromosome, making them either orange or not. In the case of white female cats, their offspring could potentially exhibit various colors if they inherit different combinations of genes from both parents.
Moreover, other genetic factors such as modifiers and dilution genes can also influence the final appearance of the kittens. Modifier genes can alter the expression of coat color genes, leading to variations in shade or pattern. Dilution genes can change the intensity of the pigment, resulting in lighter shades of the original color.
In summary, if two white cats have kittens, the exact appearance of the offspring will depend on the specific genetic makeup of each parent. The kittens could be albino with red or pink eyes, exhibit other recessive colors, or display various patterns and shades influenced by modifier and dilution genes. Understanding the genetics behind coat color in cats provides insight into the diverse possibilities that can arise from such a mating.
