Which of the following shows differences between chromosome in a cell at metaphase of mitosis with those in a cell at metaphase Il of meiosis? * I The chromosomes in metaphase of mitosis can be diploid but the chromosomes in metaphase II of meiosis always consist of a haploid set. In metaphase of mitosis, sister chromatids of each chromosome are genetically identical but in metaphase II of meiosis sister chromatids are not genetically identical. II III Individual chromosomes line up at the metaphase plate during metaphase of mitosis, but pairs of homologous chromosomes line up at metaphase plate during metaphase II of meiosis. O I and II only O I and II only Il and III only O I, Il and III
In meiosis, how does prophase I differ from prophase II? 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. 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 there is one diploid cell; during prophase II there are two haploid cells.
