Question

The correct sequence of the substages of prophase I is

• A. Leptotene$\to$ Zygotene$\to$Pachytene$\to$Diplotene$\to$Diakinesis
• B. Diakinesis$\to$ Pachytene$\to$ Diplotene$\to$ Zygotene$\to$ Leptotene
• C. Pachytene$\to$Zygotene$\to$Leptotene$\to$Diplotene$\to$Diakinesis
• D. Leptotene$\to$ Zygotene$\to$Diplotene$\to$Diakinesis$\to$ Pachytene

Answer 1

Answer: (A)

Prophase 1 of meiosis is the first stage of meiosis and is defined by five different phases- leptotene, zygotene, pachytene, diplotene and diakinesis. Leptotene is the first of five stages of Prophase 1. Second stage is zygotene. Third and fourth is pachytene, diplotene respectively. The last one is diakinesis.
So, the correct answer is 'Leptotene→→ Zygotene→→Pachytene→→Diplotene→→Diakinesis'
