b) Terminalisation of chiasmata
c) Represent transition to metaphase
Above given characteristics are related to:-
1)Metaphase I
2)Diakinesis
3)Diplotene
4)Prophase II​

Answer 1

2

sorry i dont know to explain

Answer 2

Diakinesis

Explanation:

• Diakinesis is marked by the terminalization of chiasmata.

• Chromosomes are completely condensed and preparation for separation of homologous chromosomes occurs.
• Nuclear membrane disappears and nucleolus also disappears by the end of Diakinesis.
• Re-condensation of chromosomes occurs. Spindle formation starts and the tetrad of chromosomes move towards the equatorial plate.
• Diakinesis represents transition to metaphase.
• Diakinesis is considered to be the last stage of meiosis prophase-1
• Therefore all these characteristics represent the Diakinesis phase of Meiosis-1.
