does white spotting on dogs work the same way white spotting on cats work

or is it different

how does dog white spotting work?

There's at least 3(+2) different ways of dog white spotting:

"Regular" piebald. This is a mutation of the MITF gene, and it's additive like cat white spotting: homozygotes have more white than heterozygotes. It's vaguely similar in distribution too, it's random and starts from the legs, gives blazes often and leaves the top of the head colored for last.

Irish spotting. This is recessive and much less random. Basically all irish spotted dogs look like this (the white can go up on the neck):

Whitehead. Another additive mutation, but this one starts from (you guessed it) the head; consequently this one sometimes causes blue eyes and/or deafness.

Panda. This is a KIT mutation just like the regular cat white spotting allele, and can be found only in a specific german shepherd line.

Residual white (or as we cat people call it, lockets). As far as we know, this can just happen to any dog, regardless of genetics.

A longer description of these and also from where i got the pictures

Agouti (ASIP) Gene

Some variations in the Agouti (ASIP) Gene across various species (domestic cats, dogs, rabbits and horses)

This was originally just meant for myself, but I thought I should share. Im not a geneticist, and I’m always learning, so lmk if there are mistakes!

I might do a few more species and genes, but idk, depend on what I need for my own project ^^

Anyone who thinks dogs are interchangeable really doesn't understand the nuances of genetic behavior. I know what dogs will work out in my house and what dogs won't. It's to the point that breed alone isn't enough, I only want dogs from specific lines.

I'm not "entitled and can do no wrong" for picking a certain breed and lines that you can't find in shelters. I understand quite well that not just any dog is going to mesh with me and my existing dogs. I will not try to force a dog to fit, been there done that, it's not fair to anyone involved.

I'm actually preventing more dogs from ending up in the shelter system by carefully choosing, and breeding, dogs I know will work for me and the people who need dogs of similar temperament and ability.

Abstract. Recent evidence demonstrates genomic and morphological continuity in the Arctic ancestral lineage of dogs. Here, we use the Siberi

If you have a deep fascination with sled dog genetics, breed split, and sled breed histories this is a very interesting study.

#dogblr #dog genetics #genetics study #alaskan husky #siberian husky #alaskan malamute #greenland dog #ancient dogs #this is mostly about sibe genetics #and if you liked my post about seppalas this will also be interesting to you as they are considered a subset of siberian husky in this #but for my own interests i find the closeness of the malamute participants genetics to the ancient dog examples very interesting #because we have dogs coming across from arctic asia to arctic north america in ancient history #and they spread east eventually to greenland #with malamutes being primarily descended from eastern canadian inuit dog genetics and some potential western arctic indigenous dogs #i find it makes sense they are close to the ancient examples #whereas greenland dogs have been very isolated for a long time so they're over there in the corner by themselves #further down in another graph you can see how the ancient dogs branch off from the same area as greenland dogs and malamutes #compared to other dogs #and the study does conclude that greenland dogs share the most dna with ancient wolves which is also not surprising #malamutes and greenland dogs shared significantly more ancestry with ancient dogs/wolves than siberian huskies of any population as well #while seppalas and modern chukotka sled dogs have the least

population genetics and COI is so interesting to me, especially in correlation with dog breed populations. like each breed has its own sense of normal in what percentages of pedigree and genetic COI is acceptable.

for example, this potential breeding with Ponzi technically is a light line breeding on both sides of her pedigree with pretty heavy ancestor loss after a couple generations. but bc of heavy outcrossing within those same generations, the pedigree COI is only 7% at 5 generations and only 11% at 10 generations

this is pretty low for Ibizans and remarkably low for a purebred breed in general from my understanding. we won’t know the genetic COI until I can embark a puppy, but Ponzi’s is only something like 16%

on the other hand, Spork is pretty outcrossed in pedigree, especially for a silken, but her genetic COI is 25%. Embark predicts her best pairings will produce puppies with similar COIs. Unfortunately it’s hard to compare to what the pedigree COI is as the silken pedigree database doesn’t calculate pedigree COI. From what I’ve seen, mid 20s COI is very much on the lower/normal end of things

#dog breeding #purebred dogs #dog genetics #if I had to guess - I would say Ibizans have maintained distinct pedigree lines which leads to more effective outcrossing within the breed #while Silkens tend to have a lot of the same common ancestors #distinct lines were not kept #it probably helps that Ibizans do still technically have access to COO dogs #not that ponzi has any of that super recent in her pedigree

Introduction

Hi! I’m a genetics enthusiast and specialize in researching animal color genetics! I’m by no means an expert, so while I do my best to correctly identify colors, I may be wrong!

You can submit photos of any dog, cat, horse, donkey, rabbit, or pigeon to identify its visible color (phenotype) and possible genotype! Tag me in posts, submit asks, etc!

As of now, I only have enough knowledge abt the animals listed above to determine their genetics, but I hope to expand my range (post will be updated when I do)!

Animals I’m researching: mice, rats, Guinea pigs, ball pythons, parakeets, cows, and more!

If you have a burning question abt these or any other animal, I’ll look into it!

Here’s the masterpost of all the genetic guides I’m creating!
