Brazilian Rainbow Boas are slender bodied snakes that average between 5-7 feet long. They are arguably one of the most beautiful snakes in the world. Brazilian Rainbow Boas typically range from deep red to bright orange. Rainbow Boas are well known for their amazing iridescence caused by microscopic ridges on their scales that create a rainbow glow when they reflect light. They also have bold crescent moons on their side that contrast their amazing color. These snakes is still new and has less morph same as Burmese pythons and Cornsnakes.
Before we get into the various morphs available, it’s a good idea to familiarize yourself with the terminology you’ll encounter when you read about and shop for Rainbow Boas. Bear in mind that reptile genetics (and genetics in general) is a very complex field of science, so these are very simplistic concepts.
|Recessive Traits||These are traits that come from a recessive gene. In order for recessive traits to be expressed in offspring, they must be passed on from both parents.|
|Dominant Traits||Dominant traits show up even when only one parent has the dominant gene.|
|Co-Dominant Traits||This describes an instance where an offspring displays expressions of two different but equally dominant traits|
|Phenotype||In reptiles this can be features such as scale shape and color, patterning, eye shape, and more.|
|Homozygous||Homozygous carry two copies of the same trait, one from each parent.|
|Heterozygous||Heterozygous varieties carry one copy of a normal or wild trait, and one copy of a recessive or designer trait.|
The morph are been separate into two; pattern and color morphs
Rainbow Boa Color Morph
These snakes are anything but normal looking. This simply means it’s lacking any color morphs.
The Ghost Brazilian Rainbow Boa morph is a combination of the Anery and Hypo genes
Hypomelanism is a recessive trait that reduces the dark pigments in Brazilian Rainbow Boas. This can result in the remaining color pigments appearing brighter and more brilliant than a normal animal without this genetic morph.
Anerythristic Brazilian Rainbow Boas lack red pigments. Anery are remarkable in their own right. Combining Anerythristic and Hypomelanistic color morphs to produce Ghost Brazilian Rainbow Boas.
A recessive gene that creates blotches of reduced pigment, often turning part of the snake white. This gene is thought to start displaying at sexual maturity.
A recessive gene that lacks melanin and cannot make the enzyme Tyrosinase (Albino T-), which starts the conversion of amino acid into melanin. These snakes are very light color with no black or brown markings, and have bright red eyes.
There are also the one that lacks melanin but does produce the enzyme Tyrosinase (Albino T+). These snakes are very light color with no black or brown markings, but have normal black eyes.
A trait that produces aberrant patterns.
This is a unproven gene that seems to connect and thin out the dorsal markings.
A Incomplete dominant trait that displays as dorsal striping in het form and creates an aberrant pattern with base color reduction in the homogenous state.
A dominant gene that produces a range of dark boas missing most of the saddles on the top of their body. The principals of inheritance are still being worked out.
A trait that removed the black from the snakes’ side markings leaving only a Pearl colored circle. In the extreme form (called Zebra) some animals display vertical stripes that connect the crescents and saddles.
Other morphs can be included as:
- Pastel: A recessive gene that tend to have darker markings than hypos but also have a lighter base color, often looking peach or pink colored.
- Chocolate: A dominant gene that produces an excess of brown melanin, creating chocolate brown snakes.
- Pied: The gene creates sections of white scales and changes the pattern of the overall snake to almost look like leopard print, with a complete lack of ocelot. Their eyes can range from blue to black to one blue and one black.
- Blush: A trait that expands the coloration of the oceli to creates a pink blushing effect between markings
- Bullseye: A trait that changes the oceli to become a complete circle with a small dot in the center like a bullseye target
- Eugene Stripe: A recessive gene that creates an abstract striping pattern. Is used as part of stacking genes to create Eugene’s visual Calico.
- Ted Thompson Stripe: A variable -expression recessive gene that connects the saddles together and breaks the pattern of the crescents to make long thick stripes along the top and sides of the snake.
