Genetics

Genes, alleles and colour inheritance

This genetics block shows the public educational layer only. Private pedigree data and owner details are not shown.

Trait	Gene	Alleles	Inheritance	Notes
Agouti / Black series colour	A	A, a	Black behaves as incomplete recessive in the prepared THP model.	Prepared from THP Registry calculator rules and long-term pedigree interpretation. Public summary only; raw pedigree data is restricted.
Brown dilution series colour	B	B, b	Recessive dilution model used for colour outcome calculations.	Prepared for calculator-backed colour outcomes in THP Registry.
Albino / C series colour	C	C, c	Recessive albino override in the prepared THP model.	Albino can override visible colour expression in the public model.
Grey dilution series colour	D	D, d	Recessive dilution model used for grey outcomes.	Prepared for grey and combined dilution outcomes.
Pink-eyed dilution series colour	P	P, p	Recessive model used for pink-eyed outcomes and combined colours.	Prepared for pink-eyed black, blonde and related calculated outcomes.
