I'm currently reading some introductory chapters about genetics (in Campbell's book, chapter 13) and I realized that I don't really understand what is the difference between the germ line and the germ cells.
From what I read so far, I understand that germ cells are specialized cells from which gametes are produced, and I suppose that the germ line is the "set" of all germ cells + gametes, but for some reason I couldn't find a good definition of what the germ line is and I was not satisfied with what I found in books and on the internet (because it was not as clear as I thought it could be)...
So, even if I'm ashamed to ask... Could someone explain to me the difference between those two concepts? Thanks in advance!
