自然和人工诱发的突变体往往来自较少的基因变异(大多为一个)。为了发挥这一特点,应探明其与特定发育现象密切相关的若干个突变体及其与亲本之间在形态、组织、生理生化等方面性状表达机制上的差异,并 Naturally and artificially induced mutants tend to come from fewer gene variants (mostly one). In order to exert this characteristic, we should find out some mutants that are closely related to a specific developmental phenomenon and the differences in the mechanism of expression between the mutant and its parent in terms of morphology, tissue, physiology and biochemistry, etc.
