Darwin knew nothing of genetics. (We might add that Mendel knew nothing of evolution.)

No.

Mendel, in fact, sent a reprint of his paper to Darwin.

Back then manuscripts came from the printer uncut. To read them one had to slice open the pages.

Darwin's copy of the manuscript Mendel sent him was found uncut.

Darwin never even bothered to open Mendel's manuscript.

Right, I stand corrected. (See how easy that is?)

In fairness to Darwin, he got lots of mail by that time, and Mendel remained in obscurity for years after he published.
