The dog carries the mutant gene and will pass it its entire female offspring.

The dog will develop Muscular Dystrophy (MD) and will pass the mutant gene to its entire female offspring

Clear

Genotype: N / N [ Homozygous normal ]

The dog is noncarrier of the mutant gene.

The dog will never develop Muscular Dystrophy (MD) and therefore it can be used in breeding and should only be bred to clear females.

 

Carrier

Genotype: N / MD [ Heterozygous ]

The dog carries one copy of the mutant gene and one copy of the normal gene.

The dog will never develop Muscular Dystrophy (MD) but since it carries the mutant gene, it can pass it on to its offspring.

 

Affected

Genotype: MD / MD [ Homozygous mutant ]

 

The dog carries two copies of the mutant gene and therefore it will pass the mutant gene to its entire offspring.

The dog will develop Muscular Dystrophy (MD) and will pass the mutant gene to its entire female offspring
