Genetics Behind American Wirehair’s Curly Fur

Genetics Behind American Wirehair'S Curly Fur
The American Wirehair’s unique fur has been a topic of fascination for many years. This curly coated cat breed is unlike any other, but what is the reason behind their one-of-a-kind fur? Curiosity led scientists to examine the American Wirehair’s genetics, in hopes of unraveling the mystery behind their signature feature. So, let’s dig deeper into the fascinating genetics behind the American Wirehair’s curly fur and discover how this breed’s coat differs from others. But before that, let’s explore the various color variations these amazing cats have to offer.

What is a Dominant Gene?

Genes play a vital role in determining the traits of an organism, including physical characteristics like hair color and texture. A dominant gene is a gene that can express its characteristic when present in just one of two homologous chromosomes, overriding the other allele. This means that the dominant allele will always be expressed, even if it only appears in one parent.

Examples of dominant genes include:

  • Brown eyes over blue eyes
  • Straight hair over curly
  • Attached earlobes over free earlobes

It is important to note that just because a trait is dominant, it does not necessarily mean that it is the most common trait in a population. For example, while brown eyes are a dominant trait, blue eyes are much more prevalent in certain populations.

Dominant genes can have a significant impact on the physical characteristics of an organism, as evidenced by the American Wirehair’s unique curly fur. Understanding the dominant gene responsible for this trait is key to understanding how it is passed down from one generation to the next.

Identifying the Gene Responsible for the American Wirehair’s Unique Coat

The unique coat of the American Wirehair is not just a result of a random mutation, but rather, a specific gene that has been identified by researchers. This gene, known as the Wh gene, is responsible for the wirehair coat texture of the American Wirehair breed. This dominant gene is what makes the fur of American Wirehairs stand out from other breeds.

Researchers have studied the DNA of American Wirehairs and found that this Wh gene is responsible for the wirehair texture, and that this gene is passed down from one generation to the next through simple Mendelian inheritance. In other words, if a cat inherits this gene from just one parent, it will express the wirehair coat texture.

Interestingly, this gene does not just affect the fur of American Wirehairs, but it can also affect other parts of the body such as the eyebrows, whiskers, and even the shape of the ears. However, it is important to note that this gene does not necessarily lead to the development of other wirehair features. For example, an American Wirehair that has inherited this gene from only one parent may not possess these other wirehair attributes.

The identification of the Wh gene has been a significant breakthrough in understanding the genetics behind the American Wirehair’s unique fur. It has shed light on how dominant genes can affect the physical characteristics of animals, and how they can be passed down from one generation to the next. With this knowledge, breeders can now selectively breed cats to enhance the wirehair traits, ultimately improving the overall quality of the breed.

How Breeding Affects the Expression of the Dominant Gene.

Breeding plays a crucial role in the expression of the dominant gene responsible for the American Wirehair’s unique fur. Here are some of the ways breeding affects the expression of the dominant gene:

  • Selective Breeding: Selective breeding is the process of choosing particular cats with desirable traits and breeding them together to produce offspring with those traits. Breeders can selectively breed American Wirehairs to strengthen the dominant gene responsible for the curly fur.
  • Crossbreeding: Crossbreeding is the process of breeding two different breeds to create a new breed. When an American Wirehair is crossed with a different breed, there is a chance that the dominant gene for curly fur can be diluted or lost in the offspring. Breeders must take care to select cats that carry the dominant gene to preserve the unique fur trait.
  • Linebreeding: Linebreeding is the process of breeding closely related cats to maintain a particular trait or characteristic. Breeders can use linebreeding to strengthen and intensify the dominant gene for curly fur in American Wirehairs.
  • Outcrossing: Outcrossing is the process of breeding two unrelated cats from the same breed to introduce new genes and prevent inbreeding. However, outcrossing can also dilute the dominant gene for curly fur in American Wirehairs, so breeders must select cats carefully to maintain the unique fur trait.

Breeding can have a significant impact on the expression of the dominant gene for curly fur in American Wirehairs. By selecting the right cats and breeding carefully, breeders can maintain and strengthen this unique trait in the breed.

The Complexity of Coat Genetics

Understanding the genetics behind a cat’s coat can be quite complex. For example, the American Wirehair’s unique fur is the result of a dominant gene which can be passed down through breeding. However, it’s important to note that genetics is not always a black and white matter. In fact, there are many factors that can influence the expression of specific traits.

One of the most significant factors is environmental influences. For example, exposure to sunlight can cause a cat’s fur to change color or even lighten. Additionally, diet and grooming practices can also impact the fur’s texture and overall appearance.

Another element that plays a role in coat genetics is something called “polygenic traits.” These are traits that involve multiple genes and can be influenced by a variety of factors. For example, a cat’s hair length is influenced by multiple genes, making it a polygenic trait. This is why some cats may have longer hair than others, even within the same breed.

Coat genetics is not limited to just the hair on a cat’s body. It also includes traits such as eye color and pattern. In fact, the genetics behind coat patterns such as tabby, tortoiseshell, and calico can be quite complex and involve multiple genes.

Understanding the complexity of coat genetics can be quite perplexing, even for experts in the field. Environmental factors, polygenic traits, and a variety of genes all play a role in determining a cat’s coat characteristics. While we may never fully comprehend the intricacies of coat genetics, we can appreciate the beauty and uniqueness of each individual cat’s coat.


After delving into the genetics behind the unique fur of the American Wirehair, it becomes clear that there is much more to a cat’s coat than meets the eye. The curly/wiry texture of the American Wirehair’s fur is determined by a dominant gene, which can be passed on through breeding. However, the complexity of coat genetics means that it is not always straightforward to predict the fur type of a litter of kittens.

Despite this complexity, many breeders and enthusiasts are drawn to the American Wirehair for its striking appearance and playful personality. It is important for potential owners to understand the unique needs of this breed, including regular grooming to prevent matting and possible dermatological issues.

As our understanding of feline genetics continues to grow, it is fascinating to contemplate the multitude of traits that are determined by our cats’ genes. From coat textures to eye colors and beyond, these genetic variations make each cat truly unique and special. As we continue to breed and care for our feline companions, we must strive to prioritize their health and well-being above all else.
