    1.Please refer to http://pc11.lssh.tp.edu.tw/finaldown/getfile.php?d... 有性生殖要先有不同性別的個體(mating type)的區分存在,以左圖為例,兩種不同的性別的個體會先伸出菌絲,那這兩者之間的互吸引跟人很像,它們之間有荷爾蒙的分泌,也會因為感受到荷爾蒙而互相吸引,就如同動物因為聞到荷爾蒙而相互吸引是一樣的,這種情形似乎在人身上較少見,但是動物身邊則是經常可以看的到。這樣兩邊的菌絲相互靠近之後,碰到後會在相接觸的地方形成一個2n的合子(zygote),形成之後,他又可以分裂成許多許多的mytosis以生長成下一代。
