我的基因大概等同我父親一半加上你母親一半的基因
特變不是常常發生。
我黑髮的基因我爸有、媽有、你也可能有
我紅血球基因也大體和你一樣

其實是生物學的以下定論
Hamilton's rule
rB − C > 0
where
r = the genetical relatedness of the recipient to the actor, usually (and originally) defined as the probability that a gene picked randomly from each at the same locus is identical by descent.
B = the additional reproductive benefit gained by the recipient of the altruistic act,
C = the reproductive cost to the individual of performing the act.

其中蜜蜂正是表表者,因為工蜂對蜂后的R是1(但蜂后對工蜂卻只是0。5)
配合上工蜂的C比較小,工蜂自殺去保蜂后只是為了自己基因……
