Metaphorical imperialism...

The implications of this metaphor from this BBC article are interesting.

The Y chromosome is a package of genetic material passed down from father to son, more or less unchanged - just like a surname.

Okay, I understand that writers write with an intended audience in mind, and I'm sure that the writer had in mind a specific audience for whom the metaphor works, but the writer made some interesting assumptions about that audience that could well exclude much of the world's population. It assumes patriarchal naming traditions, and there's a certain amount of a colonial attitude about it.

Just stood out to me.
