Animals humping the wrong animals
文章的意思是说动物是博爱的,只有人类是有种族歧视的。哈!
Animals really love humping and when there isn’t available a member of their own species any other that is willing is good enough! To celebrate this amazing animals’ ability to accommodate to any given condition we bring you this photo gallery of animals humping different specie of animals. Also this is a proof that only human beings can be racists
骡子(学名:Equus ferus x asinus)是马和驴的杂交种。公驴和母马的基因更容易结合,所以大部分骡子都是这样杂交的。不过基因结合的几率还是很小:有的马用了6年时间才成功的交配并使驴子怀孕。公骡子和大部分母骡子是没有生殖能力的。没有生殖能力是因为染色体不成对(63个),生殖细胞无法进行正常的分裂(即减数分裂)。母骡有性功能,子宫可以怀胚胎,但是最困难的是使母骡怀孕。严格地说,公驴和母马所产后代称为马骡;公马和母驴所产后代称为驴骡。
