Autosomal Recessive Gene Graph

                                

 

 

 

 

 

 

In order for a dog to be affected by an autosomal recessive disease, both of itís parents must be carriers of the gene.  

If TWO parents are non-affected 100% of their pups will be non-affected.

If TWO parents are affected 100% of their pups will be affected.

If ONE parent is a carrier and the other is non-affected, 50% of the offspring will inherit the gene and also be carriers, but they will not become affected.

If TWO carrier dogs are mated, 50% of their pups will be carriers, 25% non-affected, and 25% affected. 

If ONE affected dog is mated to a non-carrier, 100% of their pups will be carriers.

If TWO affected dogs are mated, 100% of the pups will be affected.

When a carrier dog is mated to a non-carrier, 50% of the pups will be carriers.
