If a black cat and a black cat have kittens, what color will they be? - briefly
If both parent cats are black, their kittens will likely also be black due to the dominant nature of the black coat gene in cats. However, it's important to note that genetic variations can sometimes result in different colors or patterns among the offspring.
If a black cat and a black cat have kittens, what color will they be? - in detail
The color of kittens born to two black cats is determined by genetics. Both parents being black does not guarantee that their offspring will also be black. To understand why, we need to delve into the science of feline genetics.
Cats have 38 chromosomes, with one pair determining coat color. The gene responsible for black fur is dominant over other colors but recessive to white spotting genes. This means that even if both parent cats are solid black, their kittens could inherit different combinations of genes, leading to various coat colors and patterns.
In the case of two solid black cats mating, there are several possible outcomes for their kittens:
-
Solid Black Kittens: If both parents carry only the dominant black gene (B), all their kittens will be solid black as well. This is because the black gene is dominant over other color genes.
-
Black with White Markings: If one or both parent cats carry a recessive white spotting gene (s), some of their kittens could have white markings on a black background. These markings can range from small patches to large areas of white, depending on the specific genetic combination inherited by each kitten.
-
Other Colors: While less common, it's possible for kittens born to two solid black cats to exhibit different colors if the parents are heterozygous for coat color genes (i.e., they carry both dominant and recessive alleles). For example, a black cat with the genotype Bb could potentially produce kittens that display other colors like brown or gray, depending on which allele is expressed in each offspring.
In conclusion, while it's common for kittens born to two black cats to be solid black themselves, there is no guarantee due to the complex nature of feline genetics. The actual outcome depends on the specific genetic makeup of the parent cats and the combinations of genes passed down to their offspring.
