The artificial flower doctrine that with German botanist Engele is a delegate thinks the flower of angiosperm and gymnospermous ball flower agree completely, every stamen and carpel, be equivalent to a male flower that degrades extremely and female flower respectively, consequently tentative idea angiosperm is to come from child plant hemp is yellow kind yellow Ephedra Campylopoda of curved handle hemp, following plan institute are shown, in this tentative idea, the bud of male flower piece turn into perianth, the bud of female flower piece turn into carpel, the small bud of every male flower piece after disappearing, remain a stamen only, female flower small bud piece ovule is remained only after disappearing, ministry of foundations of move unripe Yu Zi.
以德国植物学家恩格勒为代表的假花学说认为被子植物的花和裸子植物的球花完全一致,每个雄蕊和心皮,分别相当于1个极端退化的雄花和雌花,因而设想被子植物是来自棵子植物麻黄类的弯柄麻黄Ephedra campylopoda,如下图所示,在这个设想里,雄花的苞片变为花被,雌花的苞片变为心皮,每个雄花的小苞片消失后,只剩下一个雄蕊,雌花小苞片消失后只剩下胚珠,着生于子房基部。

Because the same sex determination gene fragment of fowl as SRY of mammal is not found, the discovered peculiar gene fragment in XhoI family will become the basic study of sex determination gene;The basis of sex differentiation is aromitic enzyme which controls sex hormone′s transformation; sex-linked inheritance and cloaca sexing will still bethe main methods of sexualization; a female can turn into a male through hormone in ducing and the changed female can turn into its genetic sexwhile a male can′t turn similarly.
家禽中虽未发现象哺乳动物SRY基因的性别决定片段,但XhoI家族中特异片段的发现可能成为性别决定基因研究的基础,性别分化的基础是控制性激素转型的芳香化酶;伴性遗传和泄殖腔鉴别法仍然是性别鉴定的主要方法;利用激素诱导只能使雌转雄而不能使雄转为雌,且转变后仍能恢复原来的遗传性别。
