They called it "infection of the germ", a neat instance of a modern sounding phrase with an obsolete meaning: the fetus permanently affecting the mother's reserve eggs. this idea was given its impressive greek name, telegony ("at a distance"and "offspring") by august weismann (1834–1914), the german biologist whose rigorous separation of somatic and germinal cells cast doubt on the inheritance of acquired characteristics. weismann believed his notion of the germ plasm could explain telegony, should it be shown to exist, but he doubted its reality.

他们称之为"细菌感染"，意思是"胎儿永久影响母亲的储备卵子"。august weismann（1834年～1914年，德国生物学家）给这一理论起了一个令人印象深刻的希腊名字， telegony （"距离"和"后代"），他仔细的分离肉体和生发细胞，对特征遗传提出质疑。weismann相信他的关于遗传物质的概念可以解释telegony，它可能是真的，但weismann怀疑其真实性。

Maize inbreds are xenial. For the hybridization along with continuous gene exchange among different plants creating a new hereditary variation pool and thereafter on the effect of natural selection and artificial selection, it creates a new germ plasm which is different from the original germ plasm at quite a large extent.

玉米是异花授粉的，在不同植株之间，由于杂交以及相伴随的连续的基因互换会创造出新的遗传变异库，其后在自然选择和人工选择的作用下，产生在相当程度上不同于原始亲本种质的新种质。

Stage I of both male and female stone flounder appears only once in all its life, and the germ cells are comprised by spermatogonia or oogonia. The gonad from Mar to Aug keeps at stage II. The gonad index of testis at this stage is 0.037%, and the amount of spermatogonia is increased quickly. There is some linear germ plasm in the cytoplasm of spermatogina. In ovary at this stage it is mostly composed by oocyte of phase 2 which the character is the appearance of yolk nucleus, and no zona radiate in membrane. The mean GI of ovary is 1.95%. From Sep to Oct gonad is at stage III which testis is composed by lots of spermatogina and few spermatocytes, and the mean GI of testis at this stage is 0.086%. In ovary the ooctyes at phase 3 are in dominate position, the yolk nucleus disappear. And the GI of this stage is 3.35%. Both testis and ovary are at stage IV in Nov. hi testis the germ cells are in spermiogenesis, and the mean GI is 0.93%. hi ovary the oocytes are mostly at phase 4, which are filled in the cytoplasm with vitellin granule, and the zona radiate in membrane begins to formation. Nucleus moves to one side of the oocyte gradually. The mean GI of ovary at this stage is 9.37%.
