ky/ky. - no copies of dominant black (allows expression of the A-Locus) Scientific References: Berryere TG, Kerns JA, Barsh GS, Schmutz SM (2005). Association of an agouti allele with fawn or sable coat colour in domestic dogs.
ky/ky. This dog carries two copies of ky which allows for the expression of the agouti gene (A locus) which can result in a variety of coat colors including sable/fawn, tricolor, tan points, black or brown. However, this dog's coat color is dependent on its genotypes at the E, A and B genes.
KB/ky. This dog carries one copy of KB and one copy of ky which prevents expression of the agouti gene (A locus) and allows for solid eumelanin (black pigment) production in pigmented areas of the dog. However, this dog's coat color is also dependent on its genotypes at the E and B genes.
ky: allows phaeomelanin (red/ yellow) pigment to show. All black-and-tan dogs or dogs with tan points are homozygote ky/ky! All fawn or sable dogs are homozygote ky/ky, whether they have a melanistic mask or not. Red dogs that have an e/e genotype however, can have any genotype at the K locus.
As a result, a dog with only one copy of the brindle gene is known as KBR/KY. KYKY is the name given to a dog with no brindle copies at all. Due to the presence of the Brindle gene, it is safe to say that Brindle can be classified as a Dominant Gene.

A kilobase (abbreviated kb) is a unit of measurement used to help designate the length of DNA or RNA. One kilobase is equal to 1,000 bases.
The KB allele is dominantly inherited and codes for a black coat colour, pheomelanin (red/light colour) cannot be produced. The kbr allele is inherited recessively and codes for the pattern "Brindle", pheomelanin can be produced at some areas.
The Kai Ken is a medium-sized dog with a wedge shaped head and prick ears. Males are typically 18 to 22 inches at the shoulder, while the females are slightly smaller, 17 to 20 inches at the shoulder. The tail may be curled over the back, or carried in a sickle position.
Just like humans, dogs can contract an upper respiratory infection that can lead to laryngitis which causes them to lose their bark or to sound hoarse. Common symptoms of the infection include lack of appetite, reddening of the ears and laryngitis.
The “Ky” Allele
The third allele is represented as "Ky.” This allele allows the agouti gene to be expressed without brindling. If a dog is Ky/Ky at the K locus, the A locus then determines the dog's coat color. The Ky allele is recessive to both KB and Kbr.
Generally speaking, puppies inherit their size from their parents. If you know how big mom and dad are, you'll have a good idea of how big your puppy will be. This is a good place to start if you're trying to estimate your puppy's future size.
Two brown dogs mated together will never throw black puppies because brown dogs do not have the black gene. But two chocolate dogs can produce yellow puppies, if each of the parents carries the little e gene – see the bottom right hand box below.
KY is short form of 空気読めない (Kuuki Yomenai) KY means being unable to read the situation or being unable to pick up on the mood of a conversation. Follow this answer to receive notifications.
Still, recent genetic studies show that bulldogs are so inbred, there may not be enough genetic diversity in the breed to eliminate some health problems. Under purebred dog rules, bulldogs can only be bred with other bulldogs, limiting the overall gene pool.
(A “supermutt” means, according to Embark, that there may be “small amounts of DNA from these distant ancestors”: chow chow, dalmatian, and miniature pinscher.)
For male dogs, Max remained the most popular name given, while Luna emerged as a new favorite choice for female dogs, according to pet care company Rover's 2022 Top Dog Names list.
The Kai Ken is a medium-sized dog and is one of the six native Japanese breeds or Nihon Ken. Traditionally used to hunt a wide range of game in the mountains of Japan, the Kai Ken is considered a rare breed even in Japan.
The dogs became a Living Natural Monument in 1933 but are still considered a rare breed in their homeland. The Kai Ken wasn't developed by humans. Instead, this Japanese pup evolved naturally and was discovered in the wild.
The Dominant Black gene (K Locus) affects pigment switching between eumelanin (black) and phaeomelanin (red or yellow) by interacting with the Agouti and MC1R genes.
KB is the dominant allele, which leads to expression of single coloured fur in pigmented areas. This trait was formerly attributed to AS of the Agouti (A) locus. There are two other alleles, kbr and ky. KB is dominant to both kbr and ky, while kbr is dominant only to ky.
Is brindle rare in dogs? The rareness of the brindle color depends on the dog breed. While brindle tends to be very rare for dogs such as Labradors and Jack Russell terriers, all Dutch shepherds are brindle.
KB/KB. This dog carries two copies of KB which prevents expression of the agouti gene (A locus) and allows for solid eumelanin (black pigment) production in pigmented areas of the dog. However, this dog's coat color is also dependent on its genotypes at the E and B genes.
The four alleles of this gene in order of dominance are: melanistic mask (Em), grizzle (Eg), black (E) and red (e). K (dominant black) locus. This gene controls dominant black, brindle, and fawn colors. This relatively new locus includes colorations previously linked to other genes like Agouti.
The only way to know the true genetic color of these dogs and the potential coat color of the puppies they could produce is to do genetic testing. There are several resources on the Internet that can help you understand color inheritance in your dog, including poodles and other breeds.
