人们分享照片，看起来他们的基因就像是复制粘贴一样

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.

遗传学之所以如此有趣，部分原因在于它们的许多影响是不可见的。但有些人可以通过简单地将自己与祖先进行比较来了解自己的生物遗传。

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.

23岁的Shelby Contra就是其中之一。最近，她在推特上发布了自己和祖母的照片，向人们展示了她们在差不多年纪时的相似之处。“就像奶奶的基因复制粘贴一样，”谢尔比在图片下面写道。

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!

她的推特迅速走红，已经有近55.5万人点赞，超过1.1万人回复。其中许多是他们自己的图像，显示了他们不可思议的跨代相似性。继续滚动，看看一些最疯狂的!
