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.
