anonymous · Answer

i think it will be crossing over

superhelp101 · Answer

Prophase 1: Chromosomes become visible, crossing-over occurs, the nucleolus disappears, the meiotic spindle forms, and the nuclear envelope disappears. At the start of prophase I, the chromosomes have already duplicated.
 Prophase II. Meiosis II begins without any further replication of the chromosomes. In prophase II, the nuclear envelope breaks down and the spindle apparatus forms
