Brindle/Reverse Brindle = Flashy Fawn?

[Kaybie's Mom]

I just have a quick question. I am pretty sure this is the appropriate section to put it in, if not, I apologize.

What are the chances of a female plain reverse brindle and a male plain brindle producing a flashy fawn pup? Just curious if this is even possible? Thanks.

Two non-dominant brindles (which both parents must have been) can certainly produce fawn pups. On average, 50% of their offspring will be fawn. There is more on coat colour inheritance at www.boxerworld.com/coat_colour

One parent being "reverse" brindle is irrelevant. That's still just brindle - all the "reverse" label is about is describing the concentration of dark stripes (genetically, however, it is no different to any other shade of brindle).

The only thing that's a bit fishy here is the flash. Two genetically plain (classic) parents cannot possibly have produced a flashy puppy. Therefore, either one of those "classic" parents is not really classic at all, but a lightly marked flashy dog; or alternatively, both of the "parents" are not the parents (ie. a different sire or dam was involved).

Thanks for the reply. This was just a hypothetical question, not one that has actually happened. I asked because I am interested in looking into getting a new puppy in the near future. I was thinking about going back to Kaybie's breeder and seeing about getting a sibling for Kaybie if they might have a litter coming up. But Kaybie's mom was the reverse brindle and Kaybie's dad was the classic brindle. I do remember that the majority of their litter was brindle but there was one male fawn pup but I can't remember if he was flashy or not. I really want a flashy fawn male pup when I get one so if that isn't even genetically possible then I think I need to find a different place to get a pup from. Thanks for the info.

There are pics of Kaybie's mom and dad in my gallery. Based on what they look like, can you tell if a flashy fawn pup would be possible?

Rocky's grandparents where both flashy brindles and his dad came out a flashy fawn. Rocky is a fawn also. Interesting, huh?

Did the mom have any white? I know with my two the father was a reverse brindle and the mom was a fawn with very little white. Out of the 8 she had one was a very flashy brindle, my Maddox and the rest, 2 Classic Fawn, 4 Classic Brindle and 1 reverse.

Can you post a link to their pictures? I took a quick look in your gallery, but didn't see them.

If they produced a fawn pup in the past, then at least you know that they're both non-dominant brindles, and can therefore produce fawn puppies (and as mentioned, on average, 50% of their offspring will be fawn. Doesn't mean every litter is going to be average though! They could have an entire litter of brindles, or an entire litter of fawns. It's just the luck of the draw).

Were there any flashy pups in Kaybie's litter? If there were, then you'd also know that at least one parent is really genetically flashy. If they're plain though, then there is no way in the world that they can ever (together)produce either flashy or white puppies.

I pulled their pictures up to the first page of my gallery so they are the first two pics. They aren't very good pictures but it's all I've got. I can't remember if the fawn pup from Kaybie's litter was flashy or not, I only saw him for a split second. So as far as I'm understanding, it's pretty unlikely, if not impossible, for Kaybie's parents to produce a flashy fawn.

Thanks And yes, they both strongly appear to be classic dogs. So unless one of them is genetically flashy but incredibly lightly marked (which is unlikely), it would be impossible for them to produce a flashy puppy.

Put simply, if a dog is classic then it has two copies of the S gene for solid coat colour. And does not carry sw for flash. You cannot pass on what you haven't got and if neither parent has sw then neither can any of their offspring. Therefore, no flashy pups could possibly be produced from this combination.

Fawn is not a problem, however

Ok thanks for the info. I was hoping to get a biological brother of Kaybie's but I have my heart set on a flashy fawn so I guess I need to start my search elsewhere. I appreciate your help.
