Vedclass · Answer

(B) Prophase-$I$ of meiosis is a complex and long phase compared to the prophase of mitosis. It is subdivided into five distinct stages based on chromosomal behavior:$1$. Leptotene: Chromosomes become visible as compact threads.$2$. Zygotene: Pairing of homologous chromosomes occurs (synapsis).$3$. Pachytene: Crossing over takes place between non-sister chromatids of homologous chromosomes.$4$. Diplotene: Dissolution of the synaptonemal complex occurs,and homologous chromosomes start to separate except at the sites of crossovers (chiasmata).$5$. Diakinesis: Terminalization of chiasmata occurs,and the chromosomes are fully condensed.Therefore,the correct sequence is Leptotene $\rightarrow$ Zygotene $\rightarrow$ Pachytene $\rightarrow$ Diplotene $\rightarrow$ Diakinesis.

The correct sequence of stages during the prophase-$I$ of meiosis is:

Similar Questions

In which phase do the chromatids separate even at the site of chiasmata formation?

Assertion : The stage between two mitotic divisions is called interkinesis.
Reason : Interkinesis is generally short lived.

Give scientific reason: Meiosis and gametogenesis are always interlinked.

In which of the following does $Meiosis$ $NOT$ occur?

$S -$ Statement: In the pachytene substage,each group of chromosomes appears as a bivalent.
$R -$ Reason: During prophase in plant cells,the centriole units arranged at the two poles form spindle fibers.
