So my Girl Sage is AY AT and she is a lilac fawn carrying tan points. When a dog receives each allele from each parent- the color patterns from each allele is still produced. AY will phenotypically show as the fawn. AT will phenotypically show as tan points. However, each phenotype is only expressed in 50% of the hairs present are coded for by each allele. Therefore its darker color coat patterns that cover the tan points AND/OR the the D locus in the lilac that lightens the coco AY locus leading to a contrast in the tan point and the lilac, allowing visibility of those hairs present. I’ll make a video to show and tag you in it.
I understand all of this , only thing that’s confusing me is why AT is recessive in English bulldog but dominant in French bulldogs. No one yet has been able to answer this.
@ The expression of the AT (tan points) allele at the A-locus (agouti gene) varies between dog breeds like English Bulldogs and French Bulldogs because of differences in how certain genes interact with each other. In genetics, dominance and recessiveness of traits often depend not just on one gene but on how it interacts with other genes that control coat color, pattern, and pigment distribution. Here’s a breakdown of some reasons why AT is expressed differently in these two breeds: 1. Breed-Specific Genetic Modifiers: Each dog breed has unique modifiers-other genes that can influence how coat color genes are expressed. French Bulldogs and English Bulldogs have distinct genetic backgrounds due to selective breeding, which can cause variations in how AT behaves. In French Bulldogs, certain modifiers may enhance the expression of AT, making it appear dominant. Meanwhile, English Bulldogs may have different modifiers that suppress or mask AT expression, making it appear recessive or less visible. 2. Impact of Other Locus Interactions: The expression of AT can be affected by other loci, such as the K-locus and E-locus: • K-locus (dominant black): Dogs that have the KB (black) allele will often mask agouti patterns like AT. If a breed carries KB commonly, AT may be less visible or recessive. • E-locus (extension): If dogs have e/e (recessive red/yellow) on the E-locus, agouti patterns are typically hidden, affecting the appearance of AT. 3. Genetic Drift and Selection: Over generations, breeders may select for certain coat patterns and colors that reinforce certain genetic expressions. In French Bulldogs, tan points are more common due to the selection of alleles that encourage AT expression, while English Bulldog breeders may have selected against visible tan points, reinforcing AT as a recessive trait. In summary, AT’s dominance or recessiveness is influenced by breed-specific genetic backgrounds, modifiers, and breeding practices. This is why AT can appear dominant in French Bulldogs but recessive in English Bulldogs. Chat GPT
Please make a video on koi, different types of fluffy, and blue eyes (husky). Ive been doing a little research trying to understand it too. Personally I respect whatever stays closer to the standard structure and behavior. A lot of these exotics coats n stuff have a poorer structure and are usually dumber and less social than the standard
Hi from Australia 🇦🇺 thanks for the information! Just had my first litter of Aussie bulldogs so learning heaps from you
Glad I could help! Congratulations!
You should have put pictures of the dogs with the colors on them
Exactly
This is a Bad ass video!!!!!!!! Wow a lot I learned, thank you!
‼️💯 Glad you enjoyed it! I appreciate the support 🤝💯
8:05 so true. I wasn’t sure it was normal until you said it 😂
‼️💯
New Shade Rojo sounds better imo and it’s my favorite color in frenchies. Great vid!

Correction, dd and bb make Isabella. dd coco make lilac
In frenchies it does yes. In English it’s different. I explained this
the kb gene? different from kbr?
Same just different labs label it differently
Which company would you recommend to get dna testing to figure out everything your dog carries, ect
Animal Genetics is who I use.
I use embark for the health and proof of breed for the parents and will be using UC Davis (bc I’m in Cali) for the puppies
@@BulldogBreeder they have so many tests, which one would you recommend?
@@dessiraeemckeever depends on what your trying to figure out. They have a breed specific health & color panel
