Its easy to understand how traits are passed on. All creatures are comprised of DNA. We get our DNA from our parents. The long coat gene is a recessive gene in a short coated dog. In a long coated dog, it is a dominant gene. Look up punnet square. A punnet square is used to predict the genotype and phenotype of offspring of two parents. For example: My bitches first litter produced 8 pups. 4 pups sable, 4 pups black. 4 pups long coat, 4 pups short coat. My bitch is black short coat. The sire is sable short coat. Both dogs carry a recessive gene for the long coat, so there was a 25% chance of long coat puppies in the litter. The black gene is also recessive, also a 25% chance of black puppies. If you dont know what genes they carry you can guess by the outcome of the puppies. This current litter of hers only produced 4 puppies, so not sure if just the small number of puppies would indicate dominant/recessive genes. She had no long coat, and no black. I know the male has a recessive black gene, his sire is black, but may not carry the long coat gene, since no long coated puppies. The gene is there, just depends on how the chromosomes pair up.
