Dog Breeding

Another part to consider on how traits are passed along are chromosomes.  A chromosome is the organized structure of DNA.  Genes are placed together in a precise order resembling long strands.  The chromosomes exist in every cell in the body.  The chromosome is paired with a corresponding chromosome; one chromosome is from the bitch and one is from the dog.  

Every chromosome consists of a lot of genetic information. Dogs have 78 chromosomes or 39 pairs.
