Dogs are able to distinguish the smell of twins

The sharp canine sense of smell allows us to distinguish even identical twins, what can not even DNA test, - convinced the researchers, and reported this in an article in the journal PLoS ONE. Briefly about this discovery tells LiveScience.

The experiment involved ten trained police shepherd-dogs. In this case, the basic requirement for the animals had the ability to distinguish smells good. The dogs were given a sniff of skin scrapings identical and fraternal twins.

Recall that identical twins develop from a single zygote, share a common placenta, the same sex and have a 100% common genotype. In fraternal twins genotype is similar to the 50%.

From this, it follows that distinguish DNA testing monozygotic twins is not possible. But dogs have coped with this task, and never made a mistake. Scientists came to the conclusion that the whole point of the finest features of the odor of each of the twins.
