In meiosis, how does prophase I differ from prophase II? During prophasel there is one diploid cell; during prophase II there are two haploid cells. During prophase I the nuclear envelope breaks up; during prophase II the nuclear envelope remains intact. O During prophase I chromosomes line up single file in the middle of the cell; during prophase II the chromosomes line up in double file in the middle of the cell. During prophase I the chromosomes coil up; the chromosomes are not coiled up during prophase II. In prophase I the sister chromatids are attached; in prophase II the sister chromatids are separated.
