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.

Brushtail possum

black

Inheritance: recessive.

Eastern quoll

melanistic

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/_). Note the ears! When otherwise not indicated, images from here.

melanic

Inheritance: recessive.

Rat

Inheritance: recessive.

Guinea pig

recessive black

Inheritance: recessive.

Tassel-eared squirrel (Abert’s squirrel)

black

Inheritance: recessive.

Rabbit

tan/otter

non-agouti

Inheritance: order of dominance is wild type > tan > non-agouti.

tan or otter, black

Dog

dominant yellow

shaded yellow

agouti (wild type but rare)

black saddle

black back (three mutation)

recessive black

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.

Red fox

dark standard silver

Inheritance: recessive.

Domestic cat & Leopard cat

charcoal (four different mutations; from the leopard cat)

non-agouti

Inheritance: recessive to the domestic wild type, intermediate with each other.

twilight charcoal (Apb/Apb), midnight charcoal (Apb/a), black (a/a)

Asiatic golden cat

black

Inheritance: (probably) recessive.

Kodkod

melanistic

Inheritance: recessive.

Pampas cat

melanistic

Inheritance: recessive.

Leopard

black (two different mutations)

Inheritance: recessive.

Cattle

brindle

Inheritance: dominant.

image source

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

white

Inheritance: dominant.

image source

Arabian camel

black and dark brown

Inheritance: unknown.

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.

Southern Pampas Cat Leopardus pajeros

A small wildcat found in Argentina and Chile. They are slightly larger than a domestic cat with a bushier tail. It is debated whether L. pajeros is a species or a subspecies.

RSL characters as Wild cats!!!

Dr. James Wilson is a Pampas cat from South America

Barry Klemper is Nagomu! A Pallas’s cat from Japan

Danny is the elusive Andean Mountain cat

Jeremy Capello is the African Caracal! Commonly known as Floppa

Neil Perry is Polly! Another Pallas’s cat from Japan!

For #Caturday:

Ceramic bottle modeled in the form of a standing feline, decorated with resist-painted motif. Gallinazo style (aka Virú culture), NW Peru, Early Intermediate Period, c. 200 BCE - 600 CE. Spotted at the American Museum of Natural History NYC.

PS: this vessel may depict the Peruvian subspecies of Pampas Cat aka Northern Colocolo (Leopardus colocola garleppi). The Andean Mountain Cat (Leopardus jacobita) is also often suggested, but their range is more southern and higher elevation than where the Virú were? Also note the stripier legs on the Colocolo similar to the ceramic:

Prideful kitty!

Happy Pride Month! Be proud of your sexual orientation!, just like this pansexual cat!

south america! the three tiger cats seem to be a recent taxonomical addition, but different ones have also been called other names such as southern and northern tiger cats and oncillas! the print is available on etsy here and as a sticker pack here
