Angelfish Genetics Calculator Online

Angelfish enthusiasts and breeders are constantly seeking ways to predict the coloration of their angelfish offspring. The Angelfish Genetics Calculator is a powerful tool that offers invaluable insights into the genetics behind angelfish coloration. It allows you to predict the outcomes of different angelfish crosses, helping you achieve the desired colors in your angelfish breeding program.

Formula with Variables Description

The calculator employs the Punnett square method, a fundamental tool in genetics, to determine the potential outcomes of genetic crosses. To understand how it works, let’s delve into the variables and genes involved:

#1 – Hong Kong Gold (hg): This gene is recessive to the wild-type and is likely no longer present in the hobby.

#2 – Smokey (Sm): Smokey is dominant to the wild-type, meaning that if an angelfish carries even one copy of the Smokey gene, it will exhibit the Smokey phenotype.

#3 – Stripeless (S): Stripeless is dominant to the wild-type, and Zebra (Sze) is also dominant to the wild-type. If an angelfish carries one or more copies of these genes, it will display their respective phenotypes.

#4 – Dark (D): The Dark gene is dominant to the wild-type, as are Marble (Dm) and Gold Marble (Dgm). However, New Gold (dng) is recessive to the wild-type. Understanding these genes is crucial for predicting the color patterns in angelfish.

#5 – Halfblack (h): Halfblack is a recessive gene. An angelfish must carry two copies of this gene to exhibit the Halfblack phenotype.

#6 – Pearl (p): Pearl is also a recessive gene, requiring two copies to express the Pearl phenotype.

#7 – Streaked (St): Streaked is a dominant modifier of the Dark gene, impacting the overall coloration of the angelfish.

#8 – Blue (b): Blue is a recessive modifier that affects the color mutations caused by other genes.

Using this notation, we can define the genotypes of various angelfish strains:

• Smokey: Sm/Sm +
• Chocolate: Sm/Sm
• Ghost: S/s+
• Blushing: S/S
• DD Black: D/D
• Black Lace: D/d+
• Zebra (one dose): Sze/s+
• Zebra Lace: Sze/s+ – D/d+

Example of Angelfish Genetics Calculator

Let’s explore an example to demonstrate how the Angelfish Genetics Calculator works. Suppose you want to predict the coloration of offspring resulting from a cross between a Chocolate angelfish (Sm/Sm) and a Zebra Lace angelfish (Sze/s+ – D/d+).

Using the calculator, you can input the genotypes of the parent fish and generate a Punnett square to visualize the potential outcomes. It will help you anticipate the color variations among their offspring, whether they’ll inherit the Smokey, Zebra, Lace, or other genetic traits.
