This supports the idea that in embryos from wild-type mothers, dpp H~- mutations cause the transformation of dorsal into ven-tral epidermis. If tissue determined to become dorsal epidermis dies in the dpp rim-null embryos, then one should not see ventral or lateral tissue formed in the double-mutant combination.
In Meiosis II, the haploid secondary germ cell (which has two chromatids per chromosome) divides into two haploid gametes each having one chromatid per chromosome. Meiosis refers to the two-stage division of one diploid germ cell into four haploid gametes. In the first division (Meiosis I), a diploid primary germ cell becomes two haploid secondary germ cells. The second divisions (Meiosis II) involves separation of double chromatids per chromosome.
