同源异型突变(homeotic mutation) 同源异型基因的突变称为同源异型突变。这种突变可致使身体某一部位的性状特征在其他部位出现,并有可能干扰机体各部分的正常发育。 由于同源异型基因在染色体上是按照纵体轴的顺序排列的，所以当某个基因发生突变之后，可能导致该基因控制的身体部位向上一个部位相似的状况发生。
这对进一步深入研究同源异型突变的花发育机理、雄性不育机理以及应用价值有着十分重要的意义。
It is very important to study further mechanism of floral development and male sterile line of HGMS as well as its practicality.
不结球白菜同源异型突变雄性不育系hgms由于花器官开裂滞后，雌蕊损伤、柱头老化致使自然结实性较差。
Because blooming hysteresis of the floral organs of HGMS and the lesion of its pistil and aging stigma resulted in bad natural fecundity.
经典的ABC模型有效地解释了花器官发育的分子机制，可以广泛地解释因同源异型基因的突变而引起的植物花器官变异。
