The merle gene modifies the dark pigment in the eyes, occasionally changing dark eyes to blue, or part of the eye to be colored blue. Since merle causes random modifications, however, both dark-eyed, blue-eyed, and odd-colored eyes are possible. Pigmentation on paw pads and nose may be mottled by pink.
Does my dog have the merle gene?
M/M dogs will always pass on a copy of Merle to their offspring. Dog has one copy of the “M” Merle allele and one negative “m” copy of Merle allele. The dog can pass either allele on to any offspring. Dog has two copies of the recessive “m” allele and is negative for Merle.
How do I know if my dog is a double merle?
Dogs with the double merle gene may be/have:
- All white in color, or have patches of merle/mottled coloring on the top half of their body – their head, back, and base of the tail.
- Light-colored paw pads.
- Have light blue, green or brown eyes, perhaps even eyes that are different colors.
What causes a dog to be merle?
The merle pattern is produced when a dog has a single copy of the M< allele. All merle dogs have the genotype Mm — meaning they have one allele for merle and one allele for non-merle. All non-merles are mm.
What color is merle in dogs?
English: Merle is a colour combination in dogs’ coats. It is a solid base color (usually red/brown or black) with lighter blue/gray or reddish patches, which gives a mottled or uneven speckled effect. Some percentage of merle puppies could have eye defects and/or could be deaf.
What breeds carry the merle gene?
The Merle pattern can be seen in various breeds, such as the Australian Shepherd Dog, Australian Koolie, Border Collie, Dachshund, French Bulldog, Louisiana Catahoula, Labradoodle, Miniature American Shepherd, Miniature Australian Shepherd, Pyrenean Shepherd, Rough Collie, Shetland Sheepdog, Welsh Sheepdog, Cardigan …
Are merle dogs more expensive?
Merle dogs of any breed are likely to be more expensive than solid-colored dogs, even though a lot of responsible breeders try to change that. Depending on how rare the merle pattern is in the breed and how much the standard price for a puppy is, your merle dog might cost up to $3,000.
What do double merles look like?
In Double Merles, the white coat is produced by a doubling up of the gene responsible for merle. Their coat pattern is characterized by light colored background and irregular spots. Merle makes melanin pigmentation less intense in random areas of the dog’s body.
Can you breed 2 Blue Merles?
A double merle is created when two merle dogs are bred together. It doesn’t matter what color merle or what breed they are. If two merle dogs are bred together, each puppy in the litter has a 25% chance of being born a double merle.
What is a ghost merle?
Dogs with cryptic merle (also called phantom or ghost merle) typically display little to no merle pattern and some may be misclassified as non-merles. The cryptic merle alleles occur in the lower end of the range (typically from 200-255, however, this range and designation varies by study).
What breeds make a merle pitbull?
Most merle pitbull puppies are bred from a pitbull and catahoula leopard mix. Merle was a natural Pitbull color, but nowadays it is very rare to find a purebred merle puppy.
Are merle dogs rare?
The merle gene is quite rare among Dachshunds, and not seen too often. It can appear in all three coat varieties: long, short and wire-haired. The AKC breed standard specifically states that merle is an allowed coloring. The smaller and more even the spots are, the higher these dogs score in conformation shows.
Can a brindle dog carry merle?
Fawn, blue, harlequin, brindle, chocolate and piebald are all recessive genes that can be carried in any color. The brindle can also carry unseen colors. Merle and black are dominant genes.
What does a blue merle look like?
Some blue merle dogs will have a mostly gray-blue coat with a few small, black patches. The most common merle pattern and the one described in most breed standards is a coat that is approximately 50 percent merle, or gray-blue, and 50 percent black patches.
Do merle dogs have blue eyes?
All merles may have blue or partially blue eyes, and pink or partially pink noses. Merle can be completely hidden by recessive red, as recessive red dogs can’t make eumelanin pigment and merle only affects eumelanin. A recessive red merle is sometimes known as a phantom merle.
