一、什么叫表型测验表型也叫表现型,是遗传与环境因素共同作用的结果。例如,窿缘桉若生长在瘠薄坚硬的土壤上,干形多呈弯曲,长在土层深厚疏松肥沃的土壤上,则通直得多,这说明窿缘桉干形的遗传性特点和易受环境影响的情况,可见窿缘桉干形曲直这种具体性状,是由遗传与环境两种因素 First, what is the phenotype test phenotype is also called phenotype, is the result of the combination of genetic and environmental factors. For example, if the eucalyptus margin grows in infertile soil, the dry shape is mostly curved and grows on the soil with deep, loose and fertile soil, which leads to much more straightforwardness. Affected by the environment, we can see that the specific traits of stem-shaped straight hole in the margin of Eucalyptus are caused by both genetic and environmental factors
