交配型

交配型（Mating type）是同种微生物中不能互相交配的亚型，可能为性别的前身^[1]。交配型常用于指涉同配生殖的生物，其配子的大小相同，没有精细胞与卵细胞之分，因此不以“雌性”与“雄性”称之，而是以不同数字、字母或“+”和“−”来表示^[1]。例如酿酒酵母负责控制交配型的基因为MAT基因（英语：Mating-type locus），因此基因的基因型不同而可分为MATa与MATα两种交配型^[2]^[3]。有些担子菌门真菌因有数个控制交配型的基因，共有多达上千种交配型^[4]。有些生物为雌雄同体，即一个个体可以同时产生雌配子与雄配子，但同时仍有交配型之分，只有不同交配型的个体之间可以交配，如许多子囊菌门真菌、纤毛虫等^[5]。

交配型在演化上出现的时间早于异配生殖^[6]。某些类群中性别可能是由交配型直接演化而来^[7]，有研究显示异配生殖的绿藻Pleodorina starrii（英语：Pleodorina starrii）中控制性别的基因与同配生殖的莱茵衣藻（英语：Chlamydomonas reinhardtii）中控制交配型的基因为同源^[8]。交配型的演化可能与基因组内部冲突有关^[9]，个体若同时自双亲细胞中获得线粒体与叶绿体等胞器，可能会发生异源胞器的竞争而使其适存度下降^[5]。
