mutated tiger

anonymous asked:

Hey so I've seen a lot of posts about high quality vs low quality phenotypic reptiles (esp like leopard geckos and ball pythons) and I was wondering what high quality vs low quality phenotypic Kenyan sand boas look like/how to tell? :)

OH BOY IS THIS A FANTASTIC QUESTION.

I have very little experience with leo morphs and genetics, so I’ll make comparisons to ball pythons.


So comparing breeding quality in BPs and sandboas is like… difficult. They could NOT be more different. Not because a quality difference doesn’t exist, but because with sandboas, we are talking about two separate gene pools: Homo/Heterozygous mutation phenotypic traits and locality phenotypic traits. The two are VERY separate, can be combined, and are bred for or against based on the goals of the specific breeder. 

Let’s start with mutation traits. The main, singular heritable traits found in sandboas are:

Anery (most common)

Albino (second most common)

Paradox (third most common)

Splash

Paint

HGW (High Genetic White)

Hypo/Ghost (this is VERY new)


The main, heritable LOCALITY trait in sandboas is:

ALL variations of stripe (wide stripe, granite stripe, pepper stripe,etc.)

ALL variations of reduced pattern EXCEPT HGW


The main, line bred/selectively bred traits in sandboas that are NOT locality specific are:

Nuclear


Locality traits:

Yellow ground color (Egyptian locality)

Rufescens (Smaller size, brown/black, very little orange, tiger, possibly gray belly scales)

Dodoma (reduced pattern of varying degrees)

Many of these traits can be combined. 

In mutations, the degree of quality is relatively objective. Let’s take a look at the first sandboa color morph: The Anery.

Look at these three examples of anery. Which would you rather breed?

There is really only one quality example of anery here: The one on the bottom! The top sandboa is VERY dirty, a trait usually avoided with anery animals. The middle animal is… just okay. Still pretty dirty, and that disrupts the stark contrast between the black and white. The bottom, on the other hand, is minimally dirty and has decent contrast. Unfortunately, as inexperienced keepers and breeders scoop up anery sandboas (you can find one for 40 dollars at shows sometimes) the quality of anery has tanked. You see a lot more animals that look like #1 and 2 than #3.

You can see the same muddied traits in albino. For example:

(From GazPythons)

(From ball-pythons.net)

Now, if we ignore the fact that the second sandboa is a paradox albino, that the second boa is on a blue background that makes the orange pop, AND I think albinos are ugly anyway, we have the following color difference:

The second sandboa has MUCH more contrast. If you bred the first animal, you’d be left with muddy, low contrast albino and het albino animals. You find this kind of thing in every sandboa morph.

On the other genetic pool, you have locality traits that can be isolated, line bred, improved, and combined with morph traits.

Let’s look at a very dramatic locality: The Dodoma.

(From Reptileforums.uk)

Note: The above snake is a high content Dodoma cross. Pure Dodoma locality snakes are very rare and kept almost exclusively by Warren Treacher and a handful of others.

The Dodoma sandboa is named for the Dodoma Valley where they are found in Tanzania. These sandboas have bred together over time to have an overall reduced pattern. This trait is genetic, but is a TENDENCY toward a specific pattern, not a morph. Dodoma crosses (usually with normal patterned KSBs) are called California Flames (Cal Flame) and look like this:

(From Russo’s Reptiles)

This Cal Flame has the almost bald Dodoma head, the soft orange/peach color, and low black markings. Dodoma animals of varying content and expression are combined with morph mutations and result in some incredible animals.

(A Dodoma Anery)

We should also understand that an animal can have Dodoma CONTENT, or exhibit Dodoma traits, but an animal CANNOT be “het” Dodoma. Dodoma is not a gene! It is a specific, naturally line bred look.

Rufescens sandboas are another locality morph. According to Warren Treacher’s The Sandboa Book, the Rufescens sandboa is a naturally occurring locality within Ethiopia. They first arrived in the US in 2002, and when bred, produce a plethora of crossed appearances.

(Rufescens female from Mason Dixon Sandboas)

When bred to other sandboas, Rufescens crosses produce…

Tiger sandboas

ALL versions of stripe

Granite 


And MORE!


Interestingly, in Rufescens content animals, stripe is a dominant trait, but when the various types of stripe are combined, they begin to get muddy like a mutation would. Tigers, though a decidedly Rufescens trait, are NOT heritable in the het/homozygous sense. They are heritable as the Dodoma pattern tendency is heritable.


So, what makes a good breeding quality locality animal? Unlike mutation color morphs, the markers of quality are less clear cut. It depends on what you are breeding FOR. It could be a new Dodoma combo, with high contrast. Perhaps a new kind of stripe. Maybe you want to create a Rufescens cross Tiger that is also an albino. If you have a PLAN with locality animals, and your animals exhibit or produce offspring that exhibit the traits you find desirable, you are on the right track.


So: In short, with morph animals you should use similar criteria that you would use with ball pythons. Is the patterning interesting? Is the contrast high? Does the animal express its color well? Do the combined genes compliment one another?

With locality and locality cross animals, you should consider how an animal fits into your plans. Does it exhibit traits you want to breed toward? Can you combine this with other traits you find interesting? Can you safely breed animals with the same traits while limiting your inbreeding coefficient? Is the animal labeled with its correct locality? (For example: ALL stripes are Rufescens crosses, but rarely labeled as such.)

So, uh. Yeah. I hope that was at least a little helpful. It’s really late and I’m going to bed.

Golden Tigers (or Golden Tabby Tigers) are an extremely rare color mutation that is thought to affect only 30 tigers in the world - all in captivity. The genetic mutation in captive tigers can be traced back to a recessive gene that was in a white tiger named Bhim. Bhim was a carrier of the gene that caused this color mutation, what is thought to be the wide band gene (a recessive trait), and was mated to his sister who also held the wide band gene. Neither of these tigers showed the characteristics of a Golden Tiger but one of the cubs did. The cub was born in 1987.

It is thought that Golden Tigers once roamed the wild but the last two were shot and killed in 1932 and only through captive breeding was this color mutation brought back.

anonymous asked:

Is there a cryptid that could have credible potential of existing that you don't personally think does exist? Even if many think it does?

I believe in 90% of the things I post. The ones I typically believe exist are ones like color mutations (Maltese Tiger), new subspecies (Adjule), out of place animals (Alien Big Cat), and extinct animals that haven’t fully gone extinct (Thylacine). The reason I think these ones exist is because history has noted that they are real. There are all kinds of color mutations in the wild that are very rare, of course there are subspecies that exist and are undiscovered, the English government recognizes many Alien Big Cats in their forests, and the Coelacanth was a fish that had “gone extinct” 65 million years ago, but one was found in 1938. Not to mention that animals we know today used to be what we now consider cryptids: gorillas, okapi, platypus, etc.

Video Games that Feature Cryptids

Jersey Devil - Playstation and PC (Jersey Devil)

This is a 3D platform game in which the protagonist is a Jersey Devil, though hit has more bat-like characteristics. The game revolves around fighting against Dr. Knarf and his army of prehistoric monsters. And mutated vegetables.

Ty the Tasmanian Tiger - Playstation 2, Gamecube, Xbox (Thylacine)

Ty is on a search for the Thunder Stones that will power the talisman which can free his family. There were three sequels to this game: Ty the Tasmanian Tiger 2: Bush Rescue and Ty the Tasmanian Tiger 3: Night of the Quinkan, Ty the Tasmanian Tiger 4 was originally released on Xbox Games for Windows 8 PC/tablets titled simply, “Ty the Tasmanian Tiger”.

Until Dawn - Playstation 4 (Wendigo)

Wendigos are the terrifying monsters in this survival horror game. It plays out like a story, where the players decisions determine who lives and dies due to choices made. The Wendigos in the game stalk the dark and freezing woods and follow legend closely, being damaged by fire and feeding on human flesh.

Since the 1800s, people have sometimes reported seeing pure white tigers, these have become known as Stripeless Tigers (or Ghost-Striped Tigers). Written descriptions can be found in many places, including the 1829 book Le Règne Animal written by French zoologist and naturalist Georges Cuvier. “A white variety of Tiger is sometimes seen, with the stripes very opaque, and not to be observed except in certain angles of light.”

However these cats are far from a mystery animal from historic documents - they are an extremely rare color morph. These tigers not only hold the genetic mutation in the pigment gene “SLC45A2″ (this mutation causes pigment changes in red and orange colors while not affecting black colors at all). They have another mutated gene on top of that one which causes them to lose the color in their stripes. 

In 2004, a stripeless white tiger was born to two normal healthy bengal tigers at a wildlife refuge in Alicante, Spain. This cub was named Artico (left photo). In 2008, another was born at Cango Wildlife Ranch, near Cape Town, South Africa. Her name is Fareeda (right photo). Fareeda is thought to be the first white tiger born in Africa, even with her lack of stripes. It is said that these tigers are two of only 20 stripeless tigers in the world, all living in captivity. 

One out every 10,000 tigers is a rare genetic mutation - a white tiger. Worldwide only about 200 are left.
Technical note: just as a challenge, I decided not to use my Pencil stylus at all, so no blur function. Water reflections the old school way. P.S. (No animals were harmed during the making of this drawing).

morality

one of the most contextually funny things I can ever remember happening in a videogame was when a friend and I were playing Army of Two 2. It has an incredibly cheesy and poorly-implemented morality system where you make idiotic decisions and get a little cutscene showing you the consequences (as an example, if you choose not to kill a particular bad guy you get a little cutscene of him going off on holiday to the beach… and then being assassinated. Yes, it’s really that awful.)

Anyway, on one mission you come across a white tiger in a cage. For some contrived reason I can’t remember, the game makes you choose between shooting it or releasing it. Just straight up releasing it into the city. (This is a war-torn third world country so I guess we don’t care about releasing adult tigers upon civilians and that’s the “good” choice, ok) Now hold on to your hat for this because this is incredible.

If you take the “good” choice, you get a cutscene of the tiger prowling the streets and eventually coming upon a car, which is parked outside a store while the driver goes in and robs the place. The tiger sneaks into the car and when the robber returns with his ill-gotten gains, he’s implied to be gruesomely gobbled up off-screen. Yes, that’s right, if you release a grown hungry tiger into a city it will become a murderous vigilante. But that’s not the part that left me rolling on the floor.

If you shoot the tiger - this is a white tiger, by the way, a mutation of the bengal tiger, it’s not it’s own “species” it’s just a bengal tiger whose genes have given it a rarer coat colour - you get a cutscene where a young woman is on her laptop, facial expression morose as she looks at an online article about white tigers. And big red letters suddenly slap onto the article saying “EXTINCT”. Yes that’s right player, by shooting a single animal in an abandoned zoo in a war-torn country you have somehow caused the extinction an entire genetic mutation of a species. GOOD FUCKIN’ JOB
