Two New Sex Determining Factors ( M V , F D ) in Housefly, (Musca domestica) Populations in Turkey


Abstract: In most strains of the common housefly, Musca domestica, sex is genetically determined by the presence or absence of a Y chromosome with a dominant male determining factor, M. Standard trains have an XX-XY mechanism. In certain laboratory and natural populations, however, neither females nor males have the Y chromosome. These non-standard populations have autosomal mechanisms for sex determination. In the present study, the existence of two new autosomal sex determining factors, M V and F D , in housefly populations in Turkey was determined.

Keywords: Musca domestica, sex determination, M factor, F D factor.
