What occurs during Prophase II?

Prophase II, the first step of meiosis II, begins with the two daughter cells produced by the first meiotic division. As in prophase I, the chromosomes are condensed. During this stage of spermatogenesis, the cells are called secondary spermatocytes, or during oogenesis, secondary oocytes.

Concept 10: Meiosis II : 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.
