| 摘 要： | 自第5白卵系中发现新的自然突变——淡赤蚁.其形态和遗传方式与Ia、sch、cm、ch、ch-2判然各异,孵化时蚁体谈赤褐色.定名为谈赤蚁(chocolate purple).基因记号 ch~D.谈赤蚁为黑蚁和普通赤蚁(ch)的等位基因,三者显隐关系为+ch>ch>Ch~D.谈赤蚁(Ch~D)对第二隐性赤蚁(ch-2)有隐性上位作用.

| Abstract: | A spontncous mutant or the chocolate parple has been discovered from white-5 egg system. Its morphological characters and hereditary mode arc different from Ia, sch, cm, ch and ch-2 apparently. The gene is marked with ch which is the allclc of+ch and ch. The relationship among three alleles is: +ch > ch> chp. The chp is recessive epistatic on ch-2. |
