Feline Inheritance - An Introduction

Ever wondered what your kittens will look like? Whether you’re a cat breeder, genetics enthusiast, or curious pet owner, understanding feline genetics can help you predict the coat colors, patterns, and genetic traits of a future litter. Our Cat Genetics Calculator simplifies this complex science, giving you accurate probability estimates based on Mendelian inheritance, Punnett squares, and real genetic principles.

Simply select the genetic traits of the mother and father cats, click “Calculate,” and let our tool analyze the possible genetic outcomes. Whether you’re looking to predict a litter’s dilution factor, tabby pattern, or white spotting, this tool gives you scientifically-backed results in seconds!

How the [Updated] Kitten Genetics Tool Works

The calculator is based on the principles of feline genetics and inheritance, using dominant and recessive gene interactions to determine the likelihood of different coat colors and patterns appearing in kittens. The updated version of the tool works in threemodes (following the idea we have used in foal coat color calculator and was appreciated by users) to cater to both beginners and advanced users as well as students and educators.

 

Basic Mode

Perfect for students learning fundamental genetics concepts. This mode focuses on essential coat color inheritance using the B gene (Black/Chocolate) and D gene (Dilution). Students can explore how dominant and recessive alleles interact to produce Black, Chocolate, Blue, and Lilac coat colors, plus the epistatic effects of the White gene.

 

Advanced Mode

Designed for deeper genetic analysis, this mode includes four key traits:

 Coat Color Genes – B gene determining Black vs Chocolate base colors
 Dilution Genes – D gene creating Blue (dilute black) and Lilac (dilute chocolate)
 Coat Length – L gene controlling Shorthair vs Longhair traits
 Agouti Patterns – A gene determining solid colors vs Tabby patterns

This mode demonstrates complex gene interactions and multiple trait inheritance patterns.

 

Educational Mode

The most comprehensive learning experience, featuring:

 Interactive Punnett Squares – Visual genetic crosses with step-by-step explanations
Four Genetic Traits – Coat color, dilution, length, and eye color
Learning Notes – Detailed explanations of dominant/recessive inheritance, epistasis, and genetic probability
Real-world Applications – Connect classroom genetics to actual cat breeding

Perfect for biology students, educators, and anyone wanting to understand how multiple genes work together in inheritance.

Understanding the Science Behind the Predictions

1️⃣ Basic Genetic Inheritance in Cats

  • Each kitten inherits one allele from each parent for key coat traits.
  • Dominant genes override recessive genes (e.g., black (B) is dominant over chocolate (b) and cinnamon (bl)).
  • Sex-linked genes, like the Orange (O/o) gene, behave differently in male and female kittens.

2️⃣ Coat Color Genetics

Feline coat color is influenced by multiple genes, including:

  • B (Black) / b (Chocolate) / bl (Cinnamon) Genes – Determine the base pigment.
  • D (Dilution) Gene – Converts black to blue, chocolate to lilac, and cinnamon to fawn.
  • O (Orange) Gene – Sex-linked gene that turns black pigment into red/ginger in males or tortoiseshell in females.
  • W (White) Gene – Masks all other colors, producing solid white cats.

3️⃣ Tabby Pattern Inheritance

Tabby patterns are controlled by the Agouti (A/a) gene and specific tabby pattern genes:
🐾 Classic Tabby (blotched)
🐾 Mackerel Tabby (striped)
🐾 Spotted Tabby
🐾 Ticked Tabby (Abyssinian-like pattern)

 

4️⃣ Probability Calculations with Punnett Squares

The tool uses Punnett squares to determine kitten probabilities based on the dominant and recessive gene combinations inherited from the parents. For example:

  • A black (Bb) parent and a chocolate (bb) parent produce 50% black and 50% chocolate kittens.
  • A diluted (dd) parent with a non-diluted (Dd) parent results in 50% diluted kittens (blue/lilac/fawn).

This ensures accurate probability distributions for each possible kitten outcome!
