In animals and in plants, the number of sexuality is correctly two and they turn into a big female gamete and a small male gamete. There are evolutional intermediates as called “isogamete” and “anisogamete” in the algae. The Ulvophyceae, Ulva compressa is at an early evolutionary stage between isogamy and anisogamy. There are four flagellar roots (1 d, 1s, 2 d, 2s) in the two gametes. The eye spot is located in the field directed in 1d and 2s. A female mating-structure is located in the same field of the eye spot whereas male one is located in the opposite side. This sex asymmetry has been revealed to be synonymous with the directivity of organelle inheritance

在动物和植物中，性的数量正确地是两个，它们变成一个大的雌性配子和一个小的雄性配子。藻类中存在着进化中间体，称为“同配子”和“异配子”。扁石莼（Ulva compressa）是石莼科的一种藻类，处于等配生殖和异配生殖之间的早期演化阶段。两配子体均具有4个鞭毛根（1d，1s，2d，2s）。眼点位于1d和2s方向的场中。雌性交配结构位于眼点的同一侧，而雄性交配结构位于相反侧。这种性别不对称性已被揭示为细胞器遗传方向性的同义词
