在果蝇中被称为“性别比例”的异常情况，其特征是与正常1:1的性别比例极端偏离，即完全或几乎完全是雌性后代（MALOGOLOWKIN and POULSON 1957; MALOGOLOWKIN 1958）。雄性缺失是胚胎阶段死亡的结果（MALOGOLOWKIN and FOULSON 1957； MALOGOLOWKIN, POULSON and WRIGHT 1959），干扰的开始时间是基因型背景的函数（POULSON and COUNCE 1959; COUNCE and POULSON 1961）。异常垂死的卵含有一种药剂，当将其引入先前正常菌株的雌性时，可将其转化为“性别比例”状态（MALOGOLOWKIN和POULSON 1957； MALOGOLOWKIN， POULSON和WRIGHT 1959）。“性别比例”女性很少存活的儿子被发现不能传播这种情况（MALOGOLOWKIN 1958）。通过类比其他“性别比例”的例子（MAGNI 1954,1956； CAVALCANTI， FALCXO和CASTRO 1957），这些男性被认为不受“性别比例”因素的影响。本文是一个实验，以测试的分布和定位的传染性“性别比例”剂，特别是在成虫的器官和组织作为第一步，在阐明剂的性质。SAKAGUCHI和POULSON于1959年给出了初步报告。
HE abnormal condition referred to as “sex-ratio” in Drosophila willistoni is Tcharacterized by extreme departures from the normal 1: 1 ratio of the sexes, i.e. either completely, or nearly completely, female progenies ( MALOGOLOWKIN and POULSON 1957; MALOGOLOWKIN 1958). Absence of males is a consequence of mortality in embryonic stages (MALOGOLOWKIN and FOULSON 1957; MALOGOLOWKIN, POULSON and WRIGHT 1959), the time of onset of the disturbance being a function of the genotypic background (POULSON and COUNCE 1959; COUNCE and POULSON 1961). The abnormal dying eggs contain an agent which when introduced into females of previously normal strains converts them to the “sex-ratio” condition (MALOGOLOWKIN and POULSON 1957; MALOGOLOWKIN, POULSON and WRIGHT 1959). The rarely surviving sons of “sex-ratio” females were found to be incapable of transmitting the condition (MALOGOLOWKIN 1958). By analogy with other instances of “sex-ratio” ( MAGNI 1954,1956; CAVALCANTI, FALCXO and CASTRO 1957) such males have been assumed to be free of the “sexratio” agent. This paper is an account of experiments to test the distribution and localization of the infectious “sex-ratio” agent particularly in the organs and tissues of adult flies as a first step in the elucidation of the nature of the agent. A preliminary report was given by SAKAGUCHI and POULSON 1959.
