Boa Constrictor Morph & Localities Guide

Boa Constrictor Guide

Boa Constrictor Morphs & Genetics
CoDominant – Mutation is visible in a normal (heterozygous) and super (homozygous dominant) form.
Dominant – Mutation is visible and identical in heterozygous or homozygous dominant form.
Recessive – Mutation is visible in homozygous recessive form. Some mutations have visual ‘hets’ for recessive mutations.
Recessive
Kahl Strain Albino- T- albino strain (lacks melanin so cannot produce tyrosinase).


Coral Albino- Line of Kahl Albinos with pinkish hues. T- albino (lacks melanin so cannot produce tyrosinase) .


Lipstick Albino- Kahl albino strain line bred for increased reds. T- albino (lacks melanin so cannot produce tyrosinase).



Sharp Strain Albino- Another strain of T- albino strain (lacks melanin so cannot produce tyrosinase).



Blonde: T+ albino strain (has tyrosinase but produces less melanin pigments thus can produce reds, browns, and grays).



VPI T+: T+ albino strain (has tyrosinase but produces less melanin pigments thus can produce reds, browns, and grays). This boa is Caramel in color.

Re: Boa Constrictor Morph & Localities Guide

BoaWoman Caramel: T+ albino strain (has tyrosinase but produces less melanin pigments thus can produce reds, browns, and grays). Reduced/absence of black pigment, generally replaced with shades of brown



CA T+: T+ albino strain (has tyrosinase but produces less melanin pigments thus can produce reds, browns, and grays). Because this is a central american boa morph it produces oranges and reds.


Anery Type 1: No red pigment. Type 1 anery is seen in columbian boas, it tends to yellow out with age and is less intense than type 2.



Square Tail: Thin connected saddle pattern similar to that of the Arabesque and a square blocked tail pattern. Base coloration can vary from light pastel to a deep orange colored pastel.


Striped: Stripe runs from the back of the head down the dorsal area and into the tail.



Anery Type 2: No red pigments. Type 2 is seen in central american boas and is more intense and does not reduce intensity with age.


Leopard: Morph is only seen in central american boas, this morph tends to stay smaller.


Blood: Morph only seen in central american boas, tends to stay smaller. Red when born, tends to brown out with age.

Dominant
Arabesque: Thin, connected saddle patterns with black flecking throughout its entire body. Background/base coloration is usually beige and can have pink highlighting.



Co-Dominant
Hypo: Drastic reduction in black pigmentation. It can be difficult to differentiate between the heterozygous and homozygous/super form, the super form usually has the tail saddles blend into a stripe.
Heterozygous form


Homozygous dominant/super form




Jungle: Blocky/striped/X patterned saddles, high yellow coloration in the tail, needle head spear marking, bold black outlining of their saddles.
Heterozygous form


Homozygous dominant/super form




Aztec: Original boa was purchased from a school teacher, genes still being explored.
Heterozygous form


Homozygous dominant/super form




Motley: Lateral striping, black underside past the vent, ladder or striped tail. Super form is lethal within first two years.
Heterozygous form

Re: Boa Constrictor Morph & Localities Guide

Boa constrictors are awesome snakes. Never really liked the albinos as much as the normals though.
