Boa Genetic Calculator

Calculate and visualize genetic combinations for Boa constrictors. This tool helps breeders and enthusiasts predict offspring morphs, understand inheritance patterns, and plan successful breeding projects.

Single Gene Calculator

How it works: Select the genetic traits for both parent snakes to see possible offspring combinations. This calculator handles dominant, co-dominant, and recessive traits.
Parent A (Female)
Parent B (Male)

Multi-Gene Calculator

Complex Genetics: Calculate offspring probabilities for snakes with multiple genetic traits. Select multiple morphs for each parent to see all possible combinations.

Boa Morph Library

Reference Guide: Browse different boa morphs to understand their genetic inheritance patterns, visual characteristics, and breeding considerations. Our database includes over 20 different morphs with detailed genetic information.
Hypo
Dominant

Hypomelanistic boas have reduced black pigment, resulting in brighter reds and browns. A dominant trait that shows with one copy of the gene.

Motley
Co-Dominant

Motley boas have a pattern with reduced or connected lateral markings. The trait is co-dominant with a super form when homozygous.

Albino
Recessive

Albino boas lack melanin, displaying white, pink, and yellow coloration. This recessive trait requires two copies to be visually expressed.

Anery
Recessive

Anerythristic boas lack red pigment, resulting in a gray or silver appearance with black patterns. Requires two copies of the gene.

Snow
Compound

Snow boas are a combination of Albino and Anery genes, resulting in a white snake with light patterns. Requires two recessive gene pairs.

Ghost
Compound

Ghost boas combine Hypo and Anery traits, creating a pale grayish snake with muted patterns. Combines dominant and recessive genes.

Jungle
Dominant

Jungle boas have aberrant patterns with broken or irregular saddles. This dominant trait can vary in expression between individuals.

Sunglow
Co-Dominant

Sunglow boas combine Hypo and Albino genes, creating a bright orange or reddish snake with minimal dark pigment and clear patterns.

Caramel
Recessive

Caramel boas have a light brownish or tan coloration with reduced dark pigment. This recessive trait creates a warm, caramel-like appearance.

Understanding Boa Genetics

Dominant traits show their phenotype when only a single copy of the gene is present. Examples include:

  • Hypo: Reduced melanin, lighter appearance
  • Jungle: Aberrant pattern with less defined saddles
  • Aztec: Unusual markings along the dorsal stripe

Co-dominant traits show a mixed phenotype in the heterozygous state and a super form in the homozygous state. Examples include:

  • Motley: Reduced pattern, especially along the sides
  • Anery: Reduced red pigment, gray appearance
  • Ghost: Combination of Hypo and Anery

Recessive traits only show when two copies of the gene are present. Examples include:

  • Albino: Complete lack of melanin, red eyes
  • Snow: Combination of Albino and Anery
  • Sunglow: Combination of Albino and Hypo
