🧬

Genetics & Inheritance

Super
The homozygous form of a co-dominant gene (e.g., a Silkback is the "Super" form of a Leatherback).

A genetic trait present in the genotype that is not currently expressed in the phenotype but can be passed to progeny.
Het (Heterozygous)
A carrier of a recessive gene that is not visually expressed.
Homo (Homozygous)
Possessing two copies of a gene, making the trait visually apparent.
Visual
A trait that is physically apparent in the dragon's appearance.
Recessive
A mutation that requires two copies (homozygous) to be visually expressed.
Dominant
A trait that is visual with only one copy of the gene inherited from either parent.
Co-Dominant
A trait where the visual appearance changes depending on whether there are one or two copies of the gene.
Expression
The degree or manner in which a genetic trait is physically manifested.
