| 1. | Genetic analysis in any organism requires stable heritable differences .
在任何生物中进行遗传学分析时总是需有稳定的遗传性状的差别。 |
| 2. | Effect of 60co irradiation on growth and genetic mutation of chrysanthemum cuttings
射线辐照菊花对其遗传性状的影响 |
| 3. | Genes are fragments of dna sequences with hereditary information . it dominates organism ' s character by protein
基因是具有遗传效应的dna片段，它控制着生物体的遗传性状。 |
| 4. | The actual mey for a given site is a moving target that will continue to change with application of improving technology and genetics
某一特定地点的实际最大经济产量是随着应用变革的技术和遗传性状而不断变化的目标。 |
| 5. | In this paper , some approaches were reviewed for the goals of genetic control including pedigrees , pedigree validation , quantitative traits and estimating genetic variability
本文紧密围绕遗传学控制的目标，从非人灵长类动物家系建立、家系确认，数量遗传性状及遗传多态性检测等方面综述了遗传学控制的实施要素。 |
| 6. | Cytoplasmic inheritance ( extrachromosomal inheritance ) the determination of certain characters by genetic material contained in plasmids or organelles other than the nucleus , e . g . mitochondria and chloroplasts
胞质遗传：由质体或非细胞核的细胞器，例如线粒体或叶绿体所携带的遗传物质决定遗传性状的遗传现象叫做胞质遗传。 |
| 7. | The diversities , of which 15 dioscorea zingiberensis local populations in characteristics of morphology , climate and physiology , showed the significant inner genetic diversities of the species of dioscorea zingiberensis . 2
本实验所选的15个地方居群在形态性状、生理性状和物候期等的多样性表现，说明了盾叶薯蓣存在着丰富的遗传性状的多样性。 |
| 8. | Characters controlled by the dna of extranuclear organelles are not inherited according to mendelian laws and are transmitted only through the female line , since only the female gametes have an appreciable amount of cytoplasm
由于细胞质大多来自母体所产生的配子，所以由细胞核外的细胞器的dna所控制的遗传性状一般只随母系而遗传，也不符合孟德尔定律。 |
