Basenji Color Question

[Quercus]

I started to write a post last night…but realized I was way too tired to even attempt As you can see, there isn't really a simple answer. But I will try to sum up.

To have a tri puppy, you need to have either two tri parents (or a trindle - tri-brindle), or two parents who carry the recessive tri...could be any color, but the gene not expressed is a tri (meaning somewhere in their ancestry there was a tricolor)

To have a red puppy, pretty much any combination of basenjis (EXCEPT tri x tri) can make red puppies; though it is really rare to have reds from black x black breeding

To have a brindle puppy, you have to have a brindle parent; this could include trindle, or black/brindle (where the dog would LOOK black because you couldn't see the stripes, but would actually carry the brindle gene)

To have a black puppy, you have to have a black parent

So, to make it interesting, you could have a four color litter of pups with these parents: Tri-factored red (looks RED, carries tri gene) x Tri factored black brindle (looks BLACK, actually has "invisible" stripes, and carries tri gene)

I think...;) There are other combinations where you could get a four color litter as well, but this is the first one I thought of.

Does that help at all? It is confusing and likely to get more confusing as breeders are becoming more interested and tolerant of a whole host of other colors and patterns in which basenjis are found in Africa.

Many people don't realize there were originally creme colored basenjis, and fawn, and blue? Over the years, breeders have bred specifically for the three (now four) accepted colors, so the other colors were lost for the most part. I think the discussion of color is fascinating. With the African imports in the llate eighties, and now in the last few years, we are now really able to explore more about the natural coloration in Basenjis.

It would still have to be generations of black to black to even guess that they were pure for black, right? Same with brindle? Is the belief still that black and brindle are on/off…I mean the recessive to brindle, is no brindle? Does that make sense?_

Lisa is correct. I should not have used the term "pure-for" in reference to blacks and brindles. I was just trying to keep things as simple as possible so the chart would be followable by most people.

Below is the same chart corrected with more appropriate terminology.

pure-for-red x pure-for-red = only pure-for-red
pure-for-red x tri-factored red = pure-for-red and tri-factored red
tri-factored red x tri-factored red = pure-for-red, tri-factored red, and tris
tri x tri = tri only
black (non tri carrier) x pure-for-red = pure-for-black and pure-for-red
black (non tri carrier) x tri-factored red = black and red
black (non tri carrier)x brindle (non tri carrier)= black, brindle, and red
tri-factored black x tri-factored brindle = black, tri, red, brindle, trindle
tri-factored black x tri factored red = black, red, and tri
tri-factored black x tri = black, tris, and suprisingly reds
red (non tri carrier) x brindle (non tri carrier)= red and brindle
tri-factored red x tri factored brindle = red, brindle, tri, trindle
tri x trindle = tri, red, brindle, trindle
tri-factored red x trindle = tri, red, brindle, trindle
black (non tri carrier) x trindle = black, red, brindle
tri-factored black x trindle = black, brindle, red, tri, trindle

and add
brindle (non tri carrier) x brindle (non tri carrier) = brindle and red
brindle (non tri carrier) x tri = brindle and red
tri-factored brindle x tri-factored brindle = red, brindle, tri, trindle

Wow - Glad you know how it works. So there are formulas for color breeding. Thanks for sharing all this info - very interesting, especially for you breeders. I had no idea.

For me, my top priorities were health, temperament, conformation and really color of the sire wasn't that important to me though I was hoping for a black female, Rally was responsible for passing on that trait.

I like the idea of breeding for health & temperment. For me, all Basenji coat colors are beautiful. A healthy, playful Basenji is what I would find most important too.

Not really, 25% of puppies in a black to black breeding should statistically be homozygous for the trait. You wouldn't really know until you bred them and only produced blacks that they were or weren't though.

Actually, although I don't know if it has been published, it is my understanding that the genes for black, brindle, not black nor brindle have been found. There are 3 possible genes for the location either Black, Brindle, or Neither with Neither being the recessive trait._

So, to make it interesting, you could have a four color litter of pups with these parents: Tri-factored red (looks RED, carries tri gene) x Tri factored black brindle (looks BLACK, actually has "invisible" stripes, and carries tri gene)

Dogs that are Black carrying brindle can only produce Blacks, Brindles, and Trindles. So in your example above, only a 3 colored litter is possible because black and brindle are at the same location.

If Rally had been tri factored, I could have had a 5 color litter with the combination that I had. Black, Brindle, Red, Tri, and Trindle.

Wow, now this sounds really neat. I would love to see pictures of these other colored basenjis specially one in blue.

Does somebody know something more about recessive black?

We do not have what geneticists consider true "recessive black". We do have modifiers that minimize the amount of tan on tris to produce dogs that are nearly all black. Most of these dogs have some tan bleeding as they age.

Here is a website with pics of one as a puppy and then at 1 year where you can see a little tan bleeding behind the ear, under the arms, and at her tuck up.

Is any body else hearing Charlie Brown's teacher right now?
LOL.

Man! How do you keep it all straight?

ROFL! I actually hear Charlie Brown's teacher when people start talking about alelles and such for genetics myself. I just have a learning issue where all that is concerned. As long as I understand the basics of color inheritance, that's all I care about.

For those who might want a refresher course on basic genetics here is a link to the powerpoint notes that I give my high school Biology students. To make it basenji related, I do use basenjis as an example.

Ooo my head hurts!

I just told my wife yesterday, "lvoss always has a very good explanation on color/genetics, she must have a biology degree or something." lol, looks like that was right on target:D Thanks for the powerpoint

ok so i'm still confused i read it over and over….my bro just got a beautiful tri puppy through a private sale. The previous owner has the parents pedigree but not the pups, which sounded ok to me but it shows both parents being red/white. So can 2 red/whites produce a tri?

[lvoss]

Yes, tri is a recessive trait so can show up even when neither parent is tri.

I bred Maggii (red and white, tri factored) to Bantu (red and white tri factored) we had a litter of 3 reds and 3 tris….

Sarah Lee of Nocturnal Kennels has the blue basenjis. They are only CKC registered because AKC does not recognize the blues. but they are really neat to see. Sarah is a very nice lady also!

There is a picture here. I believe the dams name is Isis. and then in the picture of 4 basenjis, the 3rd from the left is a blue puppy. hope to help!

Technically not correct. The dogs are not registered with the AKC because somewhere along the line breeders of these dogs chose not to register them with AKC. AKC would certainly allow a dog blue basenji to be registered, if it was a purebred basenjis that came from AKC registered dogs. We have no disqualifications in the AKC standard.

If that Blue Basenji is purebred, then it would technically be ddkkyy..or a tri with the dilute gene expressed.

Really?! Oh i thought it was because she couldnt do the blues. That is what she thought too. but that makes more sense. If the parents werent registered then neither could the puppies. Thanks for the clearification And the continued learning experience
