In Drosophila melanogaster, the P-M system of hybrid dysgenesis is a syndrome of germ line abnormalities, including temperature dependent gonadal dysgenesis (GD sterility), high rates of mutation and male recombination, which occurs in some interstrain hybrids but only from one of the two crosses. I
A family of unstable mutations at the cut locus in Drosophila melanogaster was obtained under the conditions of hybrid dysgenesis (Gerasimova 1981(Gerasimova , 1982)). The in situ hybridization experiments have shown that, in the original unstable ct Msz mutation, the 7B region of the X chromosome (
