The Homozygous Pink White results from breeding a hetero beige to a pink white and then breed the daughter back to another pink white and hopefully she will have an homo pink white baby. It is termed a homo pink white as the beige gene in the pink white pairs with the beige gene in the hetero beige, giving it two beige genes.
Note that the fur fades to white towards the base. These can be confused with Homo Beiges, which result from hetero beige being bred to hetero beige.
