Question 1
Hybrid dysgenesis in Drosophila results from:
◦ P male × M female crosses.
◦ P male × P female crosses.
◦ M male × P female crosses.
◦ M male × M female crosses.
◦ any cross.
Question 2
Integration of a retrovirus into the host cell genome occurs by:
◦ insertion of the viral RNA into the host genome, mediated by retroviral integrase, followed by repair to make DNA.
◦ insertion of the viral RNA into the host genome, mediated by retroviral integrase and host integration factor, followed by repair to make DNA.
◦ direct insertion of linear DNA copied from viral RNA, mediated by retroviral integrase.
◦ direct insertion of linear DNA copied from viral RNA, mediated by retroviral integrase and host integration factor.
◦ insertion of the single-stranded viral RNA into the host genome, mediated by retroviral integrase, followed by synthesis of a complementary DNA strand and repair to convert the RNA strand to DNA.
