comment What is genodiversity good for?
Identification of potential partners by body odors is actually selecting for different genes, not similar ones - see this article on "genetic matchmaking" for some additional details.

comment What is the difference between intrinsic and extrinsic apoptosis?
I would actually change the example to Fas/FasL, as that interaction almost always leads to apoptosis. While TNFα is pro-apoptotic in some circumstances, there are many cases where it isn't, as it is mostly regarded as a pro-inflammatory cytokine, helping to activate cells responding to infection. However, when cytotoxic cells express FasL and bind to a target cell expressing Fas (the receptor), that (almost) always leads directly to the induction of apoptosis. I just think it would be a more clear-cut example. Your choice, though :)

comment What is the difference between intrinsic and extrinsic apoptosis?
Note that the TNFR superfamily is quite large - in this Cell paper from 2001 (sorry, not open access), it lists 26 known receptors binding to at least 18 known ligands.

comment Y Chromosome in Ovary Cancer Data
Just to expand on what @Remi.b said, there is the possibility that at some point in the past, in a male ancestor, a rare event occurred where a portion of the Y chromosome somehow ended up grafted to an X chromosome (or possibly any one of the others), but didn't cause enough issues/abnormalities to be an issue, or at least noted.

comment Does the body have a gate control for pain
Speaking from personal experience, no, the body does not just focus on one area of pain, allowing only it to be felt and other injuries not to be. It just means you hurt in more places.
