Blue cat, red cat - what will the kittens be? - briefly

The color of the kittens will depend on the genetic makeup of both parents. If both cats are heterozygous for coat color, the kittens could inherit either the blue or red fur based on their individual gene combinations.

Blue cat, red cat - what will the kittens be? - in detail

The color of a cat's fur is determined by its genetics, which can be traced back through generations and influenced by various factors. When considering the offspring of a blue cat (gray) and a red cat (ginger or orange), it's essential to understand the underlying principles of coat color inheritance in felines.

Firstly, let's delve into the genetics behind these colors. The blue coat is caused by a dilution gene that affects the intensity of black pigment, resulting in a grayish-blue hue. This gene is recessive, meaning both parents must carry it for their offspring to exhibit this color. On the other hand, the red or ginger coat is influenced by another recessive gene that suppresses the production of black pigment, allowing the orange color to dominate.

When a blue cat and a red cat mate, the kittens' coat colors will depend on the combination of these genes. Since both parents carry recessive genes for their respective colors, their offspring could inherit either or both of these traits. The possible outcomes include:

  1. Blue (gray) kittens: If both parents pass on the dilution gene, the resulting kittens will have a blue coat.
  2. Red (ginger) kittens: If neither parent passes on the dilution gene, but both contribute the red gene, the offspring will be red.
  3. Calico or tortoiseshell kittens: Female cats can exhibit a mix of colors due to their two X chromosomes. One X chromosome might carry the gene for blue fur, while the other carries the gene for red fur, resulting in a calico (black, orange, and white) or tortoiseshell (black and orange) pattern.
  4. Variations in dilution: If one parent passes on the dilution gene and the other contributes the gene for red fur, the kittens might exhibit variations such as cream or light ginger, depending on the specific genetic makeup.

It's also worth noting that male cats typically have only one X chromosome, which means they can only express one color (either blue or red) unless there are additional genetic factors at play. Female cats, with two X chromosomes, have a higher chance of displaying mixed colors due to the combination of genes inherited from each parent.

In summary, the coat colors of kittens born to a blue cat and a red cat can vary significantly based on their genetic inheritance. Understanding the principles behind these genetic traits allows for a more accurate prediction of potential outcomes in feline breeding.
