Inherited traits are passed down through an animal’s genetic code which is found in the animal’s DNA—a long molecule that is present in every cell in the body. The DNA contains thousands of genes. A gene is a specific DNA sequence that leads to the expression of an inherited characteristic. For example, there are genes that determine eye color, coat color, and other body characteristics.
And while we’re used to, for example, cats with 18 toes and puppies with 2 ears, sometimes an animal’s genes decide to play a trick on us, and it comes to this world with more (or less!) of these features. Continue scrolling and take a look at this Bored Panda list, compiled to show you what genetic surprises some of our beloved creatures possess!

#4 I Adopted A Stray Dog With 2 Mouths, One Where The Ear Should Be
Toad is about 6 years old, she found her way to the shelter that I worked at several years ago. The whole staff was kind of in shock at her appearance. She was also highly aggressive when she came in. A shelter officer muzzled her and carried her to the vet clinic and while she was there being examined, it sounds goofy but literally, we made eye contact and she immediately relaxed.
That day I took her into my office to evaluate her and she immediately crawled into my lap. This big scary, insane-looking dog, just climbed into my lap and rested her head on my shoulder. I adopted her and we have been inseparable ever since.

This is one of the oldest breeds in the world and is recovering from near-extinction – in 1963, only 6 remained. Now there are 1600. They are naturally polydactyl, can close their ears to water, and bend their heads back 180 degrees.
