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.

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
