phenotype The phenotype(!)of an organism is the expression or manifestation of that genotype as it can be observed or measured; the manifestation of the genotype in the form of characteristics which is observable and measurable for example, whether or not it produces a capsule or is resistant to an antibiotic. The most common form of an organism is often referred to as the wild-type. Alterations to the genotype can therefore be seen as changes in the phenotype.(遗传性的改变可通过表型改变来观察)
The phenotype(表型) of an organism is the expression or manifestation of that genotype as it can be observed or measured; the manifestation of the genotype in the form of characteristics which is observable and measurable ,for example, whether or not it produces a capsule or is resistant to an antibiotic. The most common form of an organism is often referred to as the wild-type. Alterations to the genotype can therefore be seen as changes in the phenotype. (遗传性的改变可通过表型改变来观察) phenotype
Variation or mutation Any change to the sequence of bases(genotype) in the dna of an organism is a mutation or variation (e 变或变异) The change may be a single- base change called a point mutation or involve a much larger sequence of dna in which case it is called a multi-site mutation. DNA may be deleted, inserted, inverted, duplicated or substituted. (that means the change of structure or amount)

Modification Modification(tii 3)is the changing of phenotype occurs only on the transcriptional and translational levels but not involve the change of the genotype that is, the genetic material or the nucleotides thus it's only a ornamental alteration
Modification(饰变) is the changing of phenotype occurs only on the transcriptional and translational levels but not involve the change of the genotype , that is , the genetic material or the nucleotides, thus it’s only a ornamental alteration. Modification
Different nomenclatures/abbreviations are used for describing genes and mutations in different organisms, but in bacteria the following convention is used
