查询词典 genetic

Our results indicated that tansgene should not increase the risk of pollen-mediated escape and damage the genetic divergy, based on transgenic rice. A new fast method of risk assessement for genetic divergy was proposed. Our studies also indicated that a wide coverage of wind-dispersed pollen of Bt-transgenic rice has potential risk to sericulture in the mulberry-rice mixed cropping area of southern China.

Polymorphic loci, polymorphic frequencies, Nei's index of phenotypic diversity and Shannon index were 228, 62.81%, 0.2781, 0.4092, respectively, among Changjiang population, and 269, 74.10%, 0.3077, 0.4493, respectively, among Minjiang population. The results suggested that the two East Sea eel populations had abundant genetic variation, and the Minjiang river population was lower than the Changjiang river population, which indicated that high levels of genetic variation existed in the natural populations of Chinese Anguilla japonica.
