Vedclass · Answer

(C) The diplotene stage of prophase-$I$ is characterized by the following features:$1$. Desynapsis: The homologous chromosomes begin to separate from each other except at the sites of crossovers (chiasmata).$2$. Dictyotene stage: In some vertebrates (like human oocytes),the diplotene stage can last for months or years,which is known as the dictyotene stage.$3$. Longest phase of prophase-$I$: Diplotene is recognized as the longest sub-stage of prophase-$I$ in many organisms.Therefore,the correct characteristics are $(a)$,$(c)$,and $(f)$.

The diplotene phase of meiosis is also characterised by:
$a$. Desynapsis
$b$. Complete terminalisation of chiasmata
$c$. Dictyotene stage
$d$. Complete disappearance of nuclear membrane and nucleoli
$e$. Complete development of astral rays and aster
$f$. Longest phase of prophase-$I$
