胚胎发育是一个沿时空顺序坐标在形态上剧烈变化，既复杂又充满神秘色彩的过程，对它的研究由来已久。孟德尔（Ｍｅｎｄｅｌ，１９００）和摩尔根（Ｍｏｒｇａｎ）的遗传研究，使生物学家们开始关注突变引起体形奇特性变化的重要性。Ｂｒｉｄｇｅｓ（１９１５）阐述了果蝇...
Embryonic development is a process in which the order of space-time coordinates changes dramatically, which is complicated and mysterious. It has been a long time ago. Mendel’s (1900) and Morgan’s genetic studies have led biologists to focus on the importance of mutations that cause changes in the appearance of the figure. Bridges (1915) explains the fruit fly ...
