Question

Refer to the given stages $A, B, C$ and $D$ of meiosis $I$ and select the incorrect statement regarding them.

• A. The last stage of A is diakinesis which is marked by terminalisation of chiasmata
• B. In stage B, microtubules from the opposite poles of the spindle attach to the pair of homologous chromosomes
• C. In stage C, homologous chromosomes separate, while sister chromatids remain associated at their centromeres
• D. In stage D, nuclear membrane and nucleolus disappear, cytokinesis follows and this is called as dyad of cells

Answer 1

Answer: (D)

In stage D, nuclear membrane and nucleolus disappear, cytokinesis follows and this is called as dyad of cells

Answer 2

In the given figure $A, B, C$ and $D$ represent prophase $I$, metaphase $I$, anaphase $I$ and telophase $I$, of meiosis $I$ respectively. In telophase stage of meiosis $I$ nuclear membrane and nucleolus reappear, cytokinesis follows and this is called dyad of cells.
