Detailed explanation-1: -Dysgenesis occurs in every cell of the Drosophila. Explanation: Hybrid dysgenesis is principally a phenomenon of the germ cells. In crosses involving the P-M system, the F1 generation hybrid flies have normal somatic tissues. Their gonads, however, do not develop.

Detailed explanation-2: -Hybrid dysgenesis is a phenomenon of sterility that arises during intraspecific hybridization when TE families are absent in one strain but abundant in another [13, 14, 15, 16]. In particular, hybrid dysgenesis in Drosophila is induced when males carrying certain TE families fertilize females that lack them.

Detailed explanation-3: -hobo is responsible for the induction of hybrid dysgenesis by strains of Drosophila melanogaster bearing the male recombination factor 23.5MRF. Cell.

Detailed explanation-4: -There are 2 main classes of TEs: DNA transposons and retrotransposons. These classes are further divided into subgroups of TEs with unique structural and functional characteristics, demonstrating the significant variability among these elements.

Detailed explanation-5: -P transposable elements were discovered in Drosophila as the causative agents of a syndrome of genetic traits called hybrid dysgenesis. Hybrid dysgenesis exhibits a unique pattern of maternal inheritance linked to the germline-specific small RNA piwi-interacting (piRNA) pathway.
