On the other hand, gonochoristic reproduction produces abundant genetic variation, and creates genetic diversity.

研究还表明，两性生殖方式为银鲫种群提供了丰富的遗传变异，创造了银鲫的遗传多样性。

Second, a lot of artificial propagation experiments were performed between different gynogenetic clones to analyze whether or not genetic recombination occurs by utilizing the identified RAPD and SCAR markers. Direct molecular genetic evidence for gonochoristic reproduction was revealed in the gynogenetic silver crucian carp, and a previous hypothesis that the silver crucian carp might reproduce both gynogenetically and gonochoristically was conformed.

二是利用银鲫的克隆多样性和其种群中存在的雄性个体，设计大量的不同繁育组合，运用已鉴定的RAPD和SCAR分子标记，分析比较了不同繁育组合子代的DNA扩增情况，探讨了这些分子标记在各个交配子代中的重组分布规律。

The birthplace of migrating birds had been a controversial problem for a long time. Based on comparision within winter habitat, reproduction habitat of Grus nigricollis, reproductive physiology and the upheaval of Qingzang Plateau in the Quaternary Period. We concluded that reproductive habitat was the birthplace of the bird species.

迁徙鸟类的种系发源地一直是个有争议的问题，本文依据黑颈鹤的越冬生境与繁殖生境的对比，以及青藏高原隆升与第四纪冰川的先后、动物繁殖生理等不同证据推断，繁殖地是鸟类迁徒的种系发源地。

Morphology of sexual reproduction abortion in'High Noon', a distant hybridization cultivar of tree peonies(P.delavayi var. lutea×P. suffruticasa), was systematically investigated with light microscopy and cross. The results indicated that:(1)The stamens matured earlier than the gynoecia and pollens dispersed at the early stage of anthesis but the rate of normal 2-celled pollens were merely 2.41%.
