MUTATIONS - Colors & Blends Defined
TERMINOLOGY
Phenotype - The composition of visible, genetically determined characteristics (such as color) which may appear alike, but which may differ in genetic makeup. In other words, it is what you see.
MUTATIONS - Colors & Blends Defined
Mutation - a change in a gene, potentially capable of being transmitted. In the fur industry the term mutation refers to colors other than standard.
TERMINOLOGY
Allelic Genes - Genes that occupy the same position on a specific pair or chromosomes and control the heredity of a particular characteristic such as eye color, density or fur color.
Dominant - When a gene is called dominant, it is implying that it is dominant to the standard. In the breeding of dominants, the simple basic rule is: If you cannot see it, it is not there as there are no carriers for dominant genes. An animal that has one mutation gene is hetero, two of the same genes is homo and if they have one of one color and one of another color, they are blends.

Recessive - Opposite of dominant. A recessive gene has no effect of phenotype homozygous. A recessive is homozygous and every time it breeds it passes on its recessive gene. To produce a recessive, one must have the recessive gene in both parents; it is dependent upon what it is mated to as to what it will produce.

Double Recessive - An animal carrying two different recessive genes.
Genotype - Genes which make up each characteristic an animal possesses. Each pair of genes determines the genotype for a different characteristic although it may not be visible. This classification is made on the basis of genetic formulas.
Phenotype - The composition of visible, genetically determined characteristics (such as color) which may appear alike, but which may differ in genetic makeup. In other words, it is what you see.Heterozygous - Genetically impure, having unlike genes. An animal carrying two different color genes, one from each parent. Sometimes referred to as half-blood. An animal with one dominant and one recessive gene for a particular trait is heterozygous.
Homozygous - Purebred. When the animal inherits the same gene from both parents. It is also sometimes referred to as a full-blood.
