同子生殖

Isogamy The sexual fusion of gametes of similar size and form. It occurs in fungi and some protoctists.

同配生殖：是形态大小相同的配子间进行的有性生殖，发生在真菌和原生生物中。

In particular, it has remained unclear how oogamy arose from isogamy, a more simple form of sex in which ery similar reproductie cells take on different "mating types" but do not differentiate as distinct sperm and egg.

尤其是异配生殖如何由同配生殖转化而来，我们对此还懵懵懂懂。同配生殖是一种更为简单的结合形式，在此过程中，非常相似的生殖细胞不管三七二十一地就与不同的配子结合，都不分这些配子是"公"是"母"。

Starrii maleness eoled from the dominant sex of its isogamous ancestor.

starrii藻的雄性性别从这种藻类同配生殖祖先的负主导性别配子进化而来。

In their new work, the researchers established a genetic connection between male sexuality of an oogamous multicellular green algae species, Pleodorina starrii, and one of the mating types of its isogamous ancestor, the unicellular alga Clamydomonas reinhardtii.

在这项最新研究中，研究人员让一种异配生殖多细胞绿藻（Pleodorina starrii藻）与其同配生殖单细胞祖先（Clamydomonas reinhardtii藻）的其中一种配子类型进行雄性配子结合，从而建立两种藻类的遗传学联系。

In particular, it has remained unclear how oogamy arose from isogamy, a more simple form of sex in which ery similar reproductie cells take on different "mating types" but do not differentiate as distinct sperm and egg.

Reproduction by the fusion or conjugation of isogametes, as in certain algae and fungi.

同配生殖由同形配子的混合或接合而发生的生殖，如在海藻和真菌中进行的生殖

It was preliminarily assumed that Z〓Z〓 hybrids were fertile male, and Z〓W〓 hybrids were abnormal and sterile. Negative interactions between Z chromosome from H. assulta and W chromosome from H. armigera maybe the major reasons for abnormality of hybrids.

初步判断，正交产生的子一代中，同配性别的Z〓Z〓为有生育能力的雄性子一代，异配性别的Z〓W〓为无生育能力的畸形子一代；Z〓染色体和W〓染色体的不协调可能是造成子一代生殖器官畸形的主要原因。

However, crossing fertility between them was lower than that of mating in and in, and fertilized egg of reciprocal crossing can be incubated and produced F〓 without prezygotic isolation. Among all combinations of reciprocal crossing, crossing of wild male quail×female small-type domestic quail are proved to produce the best effect.

野生日本鸣鹑与家鹑群体之间的杂交能育性低于同种群交配水平，但可以实现正、反交，产生受精卵、孵化出杂种一代，不存在合子前生殖隔离；在所有正、反交组合中，以野雄鹑×小型雌家鹑的效果最好。

Results of interpopulation crossing test of mating, fertilization rate, embryo growth and hatchability under the condition of cage feeding indicated that:(1) due to difference in body size, morphology, habits and characteristics and reproducing season, crossing fertility between wild Japanese quail in China and domestic quail population was lower than that of intrapopulation mating, but fertilized egg through reciprocal crossing could be incubated and produced F1 without prezygotic isolation;(2) crossing of wild male quail ?female small-type domestic quail produced the best effect among all combinations of reciprocal crossings.

通过关于笼饲环境下交配行为、受精率、胚胎发育、种蛋孵化率的种群间杂交试验证明：由于体量、形态、习性、繁殖季节性的差异，我国境内的野生日本鸣鹑与家鹑群体之间的杂交能育性低于同种群交配水平，但可以实现正、反杂交，产生受精卵、孵出杂种一代，不存在合子前生殖隔离；在正反杂交组合中，以野雄鹑X小型雌家鹑的效果最好。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
