Question

Identify the stages of Prophase I, going from left to right, from the images below.

• A. Zygotene, Pachytene, Diplotene, Diakinesis, Leptotene.
• B. Diplotene, Diakinesis, Leptotene, Zygotene, Pachytene.
• C. Leptotene, Zygotene, Pachytene, Diplotene, Diakinesis.
• D. Pachytene, Diplotene, Diakinesis, Pachytene, Diplotene.

Answer 1

The correct option is C

Leptotene, Zygotene, Pachytene, Diplotene, Diakinesis.

These images of Prophase I reflect the stages in it, from left to right, as follows:

$\bullet$As chromosomes are formed and are in condensed stage, it is $\Rrightarrow$Leptotene,

$\bullet$As pairing of opposite chromosomes appear, it is $\Rrightarrow$Zygotene,

$\bullet$As bivalents are formed and crossing over is seen, it is $\Rrightarrow$Pachytene,

$\bullet$As bivalents divide and remain attached at Chiasmata, it is $\Rrightarrow$Diplotene and

$\bullet$As bivalents are separate and has a part of Chiasma, it is $\Rrightarrow$Diakinesis.

So the correct option is C: Leptotene,Zygotene,Pachytene,Diplotene and Diakinesis.
