Question:
What are the chances of identical twins within a litter?

As with humans, identical twins (known as monozygous twins) have the same DNA and therefore share the same DNA profile.  However, the scientific literature reports that the incidence of identical twins in dog litters is rare, although the data is limited.  It is therefore very unlikely that your dog will share its DNA profile with one of its siblings.  As the number of dogs on the Forensic Dog DNA Database grows, if there are lots of examples of dogs from the same litter if should help increase our understanding of the frequency of monozygosity in dogs.
