考慮這一切,我們可以說,之所以要有兩種性別,是因為雙基因體系統需要粒線體和細胞核基因的密切配合。如果配合得不好,就會妨害呼吸作用,而且細胞凋亡和發育異常的風險也會大幅增加。有兩項因素持續地在扯著配對精確度的後腿:一是粒線體DNA遠高過一般的突變率,二是細胞核基因每一代都會被性打散重組。為了確保每一代的配對盡可能的完美,讓一組粒線體基因和一組細胞核基因進行配合測試是必要的。這說明了為什麼粒線體基因必須只來自親代中的一方。如果它們來自雙親,那就會有兩組粒線體基因和一組細胞核基因配對。這就像是讓兩個體格不同的女人搭配同一個男人,三個人一起跳交際舞。不管他們的個人表現多有水準,這亂舞的三人組很容易就會摔得十二腳朝天。要跳出真正的代謝華爾滋只需要兩個舞伴──一種粒線體,以及一套核基因。

Always.
"Inspiration: That's the divine breath. It's what people count on. They reach for it, they pray for it. And quite often, just when they need it most, they get it: It's breathed into them. And now it's your turn to give it back. "
Hap. How did you get here?
I mean...
...how did I get here?
Merely by the wrong road.
I told you, your life is over...
...and anything you do for yourself is a waste of spirit, remember?
Yes, I remember.
But you didn't tell me everything, did you?
Do you know what I've been going through?
Yes.
What do you want from me, Hap?
If I'm really dead, how come I hurt so bad?
What kind of deal is this?
You said I was going back to be an inspiration.
You never said I would feel what I'm feeling.
You didn't tell me that I would...
...see Dorinda.
What do you really want from me?
We gave you a chance to say:
"I'm glad I lived. I'm glad I was alive.
"Now it's my turn to give you a hand. Let me give you what I had. "
But I also sent you back to settle with the one you love.
I sent you back to say goodbye.

Last night I felt unbelievably sad and sometimes it happens that way: a sensation comes out across the landscape into the cities and further into the window of the car as I'm coasting the labyrinths of the canyon streets.
It feels for a moment like nothing more than wind; it’s something I don’t see coming and suddenly it’s upon me and my eyes are blurring with tears and fragmented spills of neon and ghostly bodies of pedestrians and smokestacks and traffic lights and I’m gasping from a sense of loss and desire.
I can’t think of anything I am truly afraid of and I’m trying to give something unspeakable words; some of us live in big cities so we can be alone, so we can avoid ourselves, and yet by living within massive populations we can have help or love within reach if necessary.
I am fearful of something more than fear: it's something in the landscape surrounding the cities and smaller towns between here and the coast, something out there that feels so empty and it is not made of earth or muscle or fur; it's like a pocket of death but with no form other than the light one might cast upon its trail of fragments."
- David Wojnarowicz: Close to the Knives, 1991
