Hybrid dysgenesis in natural populations ofDrosophila melanogasterin Japan. II. Strains which cannot induceP-Mdysgenesis may completely suppress functionalPelement activity

Year: 1987

Type: article

Abstract: Summary Many inbred and isofemale lines derived from wild populations ofDrosophila melanogasterwere tested for gonadal dysgenic sterility, male recombination andsnwsecondary mutation. Among them, we have found strains whose dysgenic offspring show negligible sterility, and undetectable male recombination andsnwmutation. They can be considered to be neutral strains in the strict sense. Such neutral strains appear to carry only defectivePelements in their genomes. Taking the observations of Karess & Rubin (1984) into account, it is suggested that some defectivePelements retain the function necessary forPcytotype. Cytotype determination mechanisms are discussed.
