the most beautiful baby on earth
guy obsessed with bovids rambles about the Pathologic bulls for literally No reason
i don’t really have anything actually deep to say about them . i just like them a lot and wanted to talk LOL
Plus I think the Patho1/Classic soundtrack and sfx is cool in relation to the bulls . the horns in Boiny Main and Boiny Aggression are probably alluding to how bulls call . the latter’s rhythm also reminds me of a hoofed animal cantering, the closest actual visual match to it I have is this bison lol
When you are near the cattle pens or the abattoir you’ll also hear very deep, distant mooing sounds as if the aurochs are calling out which I think is sick too

Standing, the head with projecting ears and short, tapering, curving horns, almond-shaped eyes with concentric rings, prominent neck hump and dewlap, and long, straight tail reaching down to its hooves.

ASIP - Agouti Signaling Protein
ASIP is responsible for the distribution of melanin in mammals: in the presence of the functional protein, the pigment cell produces red-yellow pheomelanin instead black-brown eumelanin. Loss of function agouti mutations are one of the most common causes of melanism.
Japanese quail
lethal yellow
fawn
recessive black
Inheritance: fawn is intermediate with the wild type and recessive black, lethal yellow is, well, lethal in homozygotes, recessive black is recessive to the wild type. Lethal yellow and fawn/recessive black interaction is unknown.
manchurian (fawn/fawn), italian (fawn/[wild or black]), lethal yellow (yellow/[wild or black]) next to wild type (wild/[wild or black]), recessive black (black/black).
Western black-eared wheatear, Eastern black-eared wheatear, Pied wheatear
white-throated (two mutations, originally happened in the eastern black-eared wheatear)
Inheritance: dominant.
Western black-eared, black-throated and white-throated eastern black-eared, and pied wheatear
Chestnut-bellied monarch
melanic
Inheritance: unknown.

Inheritence: recessive.

Tasmanian devil
Kind of an exception in this collection: tasmanians devils are fixed for an ASIP variant (missing an exon compared to the closely related quolls, in a very similar way to the melanistic quoll above).

Mouse
lethal yellow
viable yellow
hypervariable yellow
intermediate yellow
several other rare yellow alleles (ex. sienna)
white-bellied agouti (apparently twenty (!) different spontaneus mutations have been found)
intermediate agouti
tanoid
black-and-tan (twenty-two different mutations)
mottled agouti
nonagouti (four mutations)
extreme nonagouti (unlike the rest here, this isn't a sponaneous mutation, but i'll include it, because it seems to be present in the fancy)
Inheritance: Lethal yellow is considered the most dominant, because all Ay/_ mice will be pure yellow regardless of the other allele. (Ay/Ay homozygotes die in the womb and get reabsorbed, so their color is impossible to observe.) Intermediate yellow (not pictured) is dominant over everything except lethal yellow. Viable yellow is somewhat codominant with the rest of the alleles, making yellow-brindled animals with variable penetrance (homozygotes can be brindled too, although more commonly they are just a bit sooty). Hypervariable yellow is codominant, the expression of the other agouti allele depends on the individual. The other yellow alleles (not pictured) are less documented, but they are probably dominant over the non-yellow alleles. Light-bellied agouti is completely dominant over all the remaining alleles; the intermediate agouti allele, otherwise indistinguishable of light-bellied agouti, is intermediate with nonagouti. The wild type agouti is codominant with black-and-tan and tanoid alleles (making phenotypically basically light-bellied agoutis) and dominant over the nonagoutis. Tanoid (not pictured) is dominant over the remaining three, tan is dominant over both nonagouti, and the "simple" nonagouti is dominant over the extreme nonagouti.
lethal yellow (Ay/_), agouti brindle (aka viable yellow on agouti) (Avy/A), black brindles with variable expression (aka viable yellow on nonagouti) (Avy/a), hypervariable yellow litter (Ahvy/_), agouti fox aka light-bellied agouti (Aw/_), agouti (A/_), agouti tan (A/at), black tan (at/_), extreme black (ae/ae) and black (a/_).

Inheritance: order of dominance is yellow > shaded yellow > agouti > saddle = black back > black. Black saddle and black back are intermediate with each other.
Dominant yellow aka clear sable (DY/_), shaded yellow or sable (SY/_), agouti (AG/_), black saddle or saddle tan (BS/[BS or a]), creeping tan (BS/BB), black back aka black-and-tan (BB/[BB or a]), recessive black (a/a). All images from here.

Zebu
dark
Inheritance: intermediate.
Based on the paper describing the mutation, i think these could be examples of a heterozygote and a homozygote (the wild type is completely white).
Water buffalo

Inheritance: dominant.

Sheep
white (and tan)
recessive black (two mutations)
more suspected but not yet found alleles (light badgerface, badger, black&tan, light blue, swiss markings, blue, gray, lateral stripe, english blue, dark blue, paddington blue, etc)
Inheritance: i have to assume it's similar to goats. See there.
white (white/_), black (black/black) with wild type (note the light belly and chin)
Goat
white/tan/gold - so, solid pheomelanin
peacock
bezoar (wild type, but rare)
swiss markings
badgerface (blackbelly)
more suspected but not yet found alleles (black mask, grey, lightbelly, lateral stripes, mahogany, red cheek, nonagouti/black, etc)
Inheritance: every allele puts its respective phenomelanistic parts on the phenotype; so they are all codominant. In practice this sometimes becomes seemingly dominant-recessive, when one pattern completely "covers" another (for example between the pictured alleles, swiss markings doesn't add more tan to a bezoar, so bezoar/bezoar will look the same as bezoar/swiss). This makes white/tan the most dominant and solid black the most recessive.
Note that this gene only determines the shape and size of the black patches, and the color of the rest of the goat (white or brown, depending on pheomelanin intensity) is determined by other genes!
white, badgerface, bezoar, peacock, swiss marked - these are all homozygotes. I'd love to include heterozygotes too, but i couldn't find a good source, and i'm not confident enough to id on my own. If anyone can help me with either, i'd be very grateful.
