- Curliness, length, shedding, and texture - each canine coat trait is influenced by a different gene. But that’s not all; these genes work together, creating a lot of variation in the types of coats dogs can have. Learn more, as Dr. Boyko explains how a Poodle coat is genetically different from a Labrador Retriever coat, and what happens when breeds and coat types are mixed together.

Entertaining and informative. Needed the smiles, giggles and diversion this video provided.
Update: There has been a lot of feedback on this video which is intended to teach the concepts of inheritance to students. Thanks! A few keen-eyed observers have noted that Wagner, the brown and white dog, is technically “recessive red” (ee genotype). You’re right! Embark has a professional introduction into dog coat color genetics here you should definitely check out -> embarkvet.com/resources/dog-breeders/science-corner-coat-color-genetics-101/.
Notably, this isn’t the only simplification in the video. “Every puppy gets one copy of every gene from its mother and one copy from its father” is also not accurate in a technical sense as it does not describe the inheritance of the X chromosome, the Y chromosome, the Mt chromosome, chromosomal abnormalities, structural variation, chimerism, cloning or gene editing. The breeds discussed in the video are also not all technically 100% fixed for all three coat variants described in the video (it is difficult to fix a dominant trait in a breed). Additionally, not all the genes discussed are dominant in the strict sense (one copy of the gene yields an identical phenotype as two copies of the gene). There are so many interesting aspects to genetics, it’s impossible to cover them all in six minutes!
IMPORTANTLY, if you are planning on breeding a recessive red dog, please recognize that recessive red masks merle. If you breed a recessive red dog like Wagner to a merle dog like Sprightly, you risk creating double merle offspring if the red dog carries a hidden merle gene. Fortunately, this isn’t an issue here (Wagner does not carry the merle gene).
This video is a resource for middle and high school students to understand inheritance and not a complete introduction to dog coat colors and their interactions, something that requires delving into each of these genes (and many others) with much more precise language.
Why did I refer to a recessive red dog as brown and white? I asked my son and daughter (5th grade and 7th grade) what color the dog was and they both said “white and brown”. To them, Clifford is a red dog, not Wagner.
Thanks for watching!
ee creates a tan to white coat, not brown. Brown is controlled in the B locus and only occurs if the dog has EE/Ee to allow for dark coat.
Brown is b/b (also called liver, or chocolate), not e/e, recessive red. I know this was designed for the layperson but it will create more confusion in the long run, especially when people inevitably use Embark as a reliable source.
Nicely done. Thanks
Poodles do not carry merle. That was probably an Aussie doodle...
Can I ask what breeds can the recessive black be found in?
Incorrect information beginning about 4:45. The E-locus does not alter black on a dog. This is merely a "coat of paint" but the dog's true colors still show in the nose, lips, paw pads, and eye rims. The B-locus modifies black such that black is unable to express. The nose, eye rims, lips, and paw pads will be brown. The D-locus dilutes either black OR brown. Regardless, if a brown or dilute dog also has recessive ee, the dog's nose, eye rims, lips, and paw pads will be black or brown or dilute but the rest of the dog will be whatever shade of white, yellow, or red given by the two copies of recessive e. Please address the misinformation in this video.
Could you make a video or include a segment in a video about haplogroups/types? What is the difference between the two. Also, is there a way to see a list of all the breeds that Embark has seen each of the haplogroups/types in? Lastly, is it possible to know which allele was inherited from which side of the family tree/which chromosome the trait comes from/which breed in a mixed breed contributed which allele? Thank you! I'm enjoying the videos/activities Embark is supplying in this very strange time globally!
Our scientists are actually working on a manuscript on haplotype distributions now; we can try to make a video when they study is complete and published. Unfortunately except for Y, Mt and (sometimes) X, the DNA sequence can't tell us which allele what inherited from which parent. We can use haplotype information to infer which breed or population the allele was inherited from, but if the parents overlap in their breed composition, or if the parent's breed composition is unknown, it's not possible to know which parent contributed which allele without testing the parents.
@@adamboyko1181 Very interesting. Thank you for the response! I look forward to Embark's ongoing work, research, and discoveries!
Very incorrect information in regards to the E locus and Black and Brown which are dependent on the B locus.
A dog who is e/e - Recessive Red (Yellow) on the E locus can be either Black - B/* or Brown - b/b.
Very confusing to offer incorrect information.
I love that you made a video, but the information is incorrect. A dog who is ee on the E locus is red, not brown. A brown dog would not have black skin, but rather liver colored skin and brown hair. A brown dog is bb and has at least one E gene on the E locus. Wagner is red and white. He's BB or Bb and ee.
Hi Embark, I don’t think it’s accurate to call an ee dog “brown”. It’s not brown to a lay person. It’s yellow or cream. Most people think of chocolate lab color when they hear “brown” to describe a dog.
Please do not refer to tones of an ee dog as "brown". This will only lead to confusion for people whom are learning basic genetics as the "brown" term is reserved for the resulting modification tone of the B locus. I mean yes u need to simplify things but u should also be trying to keep it as accurate as possible and not lead people down a path that where they end being more confused from you using a term for ee that actually applies to another loci. If u must call it a laymen color, use the term "tan" instead of "brown".
It sucks because that dog actually IS brown. It has brown nose and eye rims, so genetically it's brown based. BUT the coat is being modified by the E locus to change the coat from Eumelanin Brown pigment to Red/Yellow Phaeomelanin pigment. Please don't describe a non-brown dog as being brown. Use cream or red or yellow!
As many others have mentioned ee is recessive red (called yellow in some breeds) there is no breed of dog that calls ee "brown" so it makes absolutely no sense to use this term in an educational video. Red, yellow, cream, white, approcote, and lemon are all used to describe ee, red being what is used in genetic labs. But brown is never used and also does not accurately describe the color from say, a crayola crayon point of view either.
Merle is not dominant. It is incomplete dominant. Children commonly learn the definition to incomplete dominant around 5th grade (about 11 years old) so its not too complicated for a beginner video. The long hair a poodle has is called furnishings. It is not called wire haired by labs or lay people. It also does not feel wirey (wires are stiff and pointy) and so it makes no sesne to usr the term wire coat in place if furnishings. It also doesn't describe the difference between long hair and furnishings as being hair everywhere Vs. Long hair only on the body and upper legs.
The white from piebald on the last pup came equally from both the pups sire and dam since piebald requires 2 copies to express in such a manner. So stating that the pup got its white from the sire is misleading.
This could have been a very good video, but it needs Alot of editing. Its just a mess.
That’s not a labrador/poodle mix. Very disappointed, neither a poodle nor larbrador Carrie the Merle gene so they can’t have Merle puppies. That puppies more than just a poodle and Labrador🤦🏼♀️
I see many comments here about the various incorrect terms being used in this video. I want to add my two cents, but instead of pointing out the errors respectively, I will just call it what it is- This video is pure trash. Embark, I am so disappointed with you on this.
