Arrange the sequence of meiosis in correct order.

Easy

A

Crossing over $\to$ Separation of homologous chromosome $\to$ Bivalent chromosomes align on the equatorial plate $\to$ Formation of dyad of cells
B

Crossing over $\to$ Bivalent chromosomes align on the equatorial plate $\to$ Separation of homologous chromosome $\to$ Formation of dyad of cells
C

Bivalent chromosomes align on the equatorial plate $\to$ Separation of homologous chromosome $\to$ Crossing over $\to$ Formation of dyad of cells
D

Crossing over $\to$ Bivalent chromosomes align on the equatorial plate $\to$ Formation of dyad of cells $\to$ Separation of homologous chromosome

Solution

Correct sequence of events occurring during meiosis is:
Crossing over $\to$ Bivalent chromosomes align on the equatorial plate $\to$ Separation of homologous chromosome $\to$ Formation of dyad of cells
Crossing over occurs during pachytene stage of meiosis-I. During metaphase I bivalent chromosomes align on the equatorial plate. During anaphase I separation of homologous chromosome takes place. During telophase I the nuclear membrane and nucleolus reappear, cytokinesis follows and this is called as dyad of cells.
