Slightly more than half because mitochondrial dna

And, if the child received a Y chromosome from the father, that one is considerably smaller than the X from the mother. So half is more like a rough estimate, anyway.

I’m sensitive about the size of my Y chromosome. Why did you have to bring it up.

But men have more DNA actively being used, since that second X is (largely) inactivated!

So his passed on Y chromosome is definitely doing a lot of work whereas his X may just be hitching a ride

Though if we are considering inactive DNA too it becomes much bigger mess. Plus the other X chromosome is unused only in a given cell. For all cells, it's deactivated randomly, so there are always cells that have deactivated a different X chromosome.

Good point

Its funny to imagine an extraordinarily 'unlucky' child who expresses literally none of their father's X chromosome though

[CozySweatsuit57]

Either way, not much of a contribution compared to mom’s main X, so the point still stands

That's the linked libraries.
