I might miss the point, but the height is dependent on both parents genetically, so just comparing mothers with daughters is a bit like the usual "correlation does not equal causation" thingie, or not?

The X and Y are just labeled weird, both graphs reference father's height has the X and mother's height as the Y

Yeah, but there is no graph comparing son vs mother and daughter vs father.

And it seems like an odd thing to omit.

If I'm reading the referenced link right, the data is from 1886(?), so it's not terribly recent, either.

Wow, thanks for checking on that

[–] [email protected] 1 points 5 months ago

yes, 928 children and 205 parents it seems.

wonder how the trend shown here has changed in almost 150 years...

Oh, completely missed that, thanks!
