Genotype: N / N [ Homozygous normal ]
The cat is noncarrier of the mutant gene.
It is very unlikely that the cat will develop Alpha-Mannosidosis (AMD). The cat will never pass the mutation to its offspring, and therefore it can be bred to any other cat.
Genotype: N / AMD [ Heterozygous ]
The cat carries one copy of the mutant gene and one
copy of the normal gene.
It is very unlikely that the cat will develop Alpha-Mannosidosis (AMD) but since it carries the mutant gene, it can pass it on to its offspring with the probability of 50%.
Carriers should only be bred to clear cats.
Avoid breeding carrier to carrier because 25% of their offspring is expected to be affected (see table above)
Genotype: AMD / AMD [ Homozygous mutant ]
The cat carries two copies of the mutant gene and
therefore it will pass the mutant gene to its entire offspring.
The cat is likely to develop Alpha-Mannosidosis (AMD) and will pass the mutant gene to its entire offspring
