Part of what makes genetics so interesting is that a lot of their effects aren't visible. But some people can learn a lot about their biological inheritance by simply comparing themselves to their ancestors.

Shelby Contra, 23, is one of them. Recently, she tweeted photos of herself and her grandmother to show just how similar the two looked when they were about the same age. "Grandma's genes really hit copy n paste huh," Shelby captioned the pics.

Her tweet went viral and nearly 555K people have already liked it, leaving over 1.1K responses. Many of which are their own side-by-side images that show their uncanny cross-generational resemblance. Continue scrolling and check out some of the craziest ones!

There's still enough difference around the chin and lips, but very close indeed

I have a hereditary gap in my eyebrow. It’s a portrait of my great great grandfather on the left, my dad also has the gap as well. It doesn’t always show, I guess because my eyebrows are kinda unruly and curly so sometimes the gap is covered, I also sometimes fill them especially because I’ve had people ask if I shaved the gap to be “cool”.

All the people that are spreading hate need to shut up! I'm 12 years old and I'm more responsible than u guys are!? You are adults spreading hate to people on social media like 5 year olds while I'm here about to make some money!!! You people are sickening and devils. I CAN'T believe the fact that you have to have a 12 year old girl tell you right from wrong in this manner. It's really sad!
