The Grandmother Thread

Ever feel like you and your grandkids just… get each other? Turns out there might be real biology behind that feeling, specifically for paternal Grandmothers of granddaughters.

Here’s the fun bit of science: a dad only has one X chromosome, and he got the whole thing from his own mother, nothing from his father. So when he passes that X on to his daughter, it arrives untouched by his dad’s side entirely. It’s like a family recipe that skipped a generation of substitutions and came out exactly as the original cook made it.

On average, you share about 25% of your DNA with any grandparent, that’s just how it works. But with a paternal grandmother, part of that 25% travels a private lane no other grandparent gets to use: the X chromosome, passed to her son whole and untouched by his father, then passed whole to his daughter. It’s not more DNA, it’s a purer line.

So next time your daughter or granddaughter says she takes after her dad’s mum, she might be more right than she knows.
