Flbaynslay, please research genetics.
It is NOT a gene like glass eyes or leopard color.
It is a recessive gene.
Please reconsider your tact, if you tell someone to "research genetics" you should validate your opinion with scientific evidence. Glass eyes and leopard coats can also be recessive genes, I have owned several catahoulas that the general public would think were underfed black labs.
any trait that didn't come out in a particular dog but was present in previous parentage is currently recessive. Remember, AA Aa. If one dog carries aa and the other carries Aa or AA what happens?
