What Happens in Prophase II? Prophase II is the stage of meiosis when the nuclear membrane breaks apart and the spindle apparatus is formed. It is the first stage of the second meiotic division (meiosis II) and follows telophase I. Meiosis is a process of cell division that is necessary for sexual reproduction. It takes place in two stages, and ...
Prophase II, the first step of meiosis II, begins with the two daughter cells produced by the first meiotic division (see figure right). As in prophase I, the chromosomes are condensed. During this stage of spermatogenesis, the cells are called secondary spermatocytes, or during oogenesis, secondary oocytes.
What Happens During Prophase II? Meiosis II occurs in both daughter cells that were formed during meiosis I. As no DNA replication takes place in this second step of meiosis, the cell division process immediately begins. Prophase II prepares the cell for secondary meiotic division where two haploid cells eventually form four haploid cells, each containing half of the genetic information ...

There are two successive divisions, meiosis I and meiosis II, in which four daughter cells that have the haploid chromosome number (23 in humans) are formed. As in mitosis (somatic cell division), meiosis I and II are each divided into four phases: prophase, metaphase, anaphase, and telophase. adj., adj meiot´ic.
Thanks A2A Prophase II meiosis is similar to prophase of mitosis. It is characterize by 1. Chromatin get condensed and thickened to form chromosomes. 2. Both the chromatids get separate but are attached to each other at a point called centromere o...
Prophase II of meiosis is very similar to prophase of mitosis. The most noticeable difference is that prophase II occurs with a haploid number of chromosomes as opposed to the diploid number in mitotic prophase. In both animal and plant cells chromosomes may de-condense during telophase I requiring them to re-condense in prophase II.
What happens in prophase 2 of Meiosis 2? nuclear envelop disappears, chromosomes condense, centrioles move apart and spindles start to form. What happens in metaphase 2 of meiosis 2? chromosomes with sisters line up in the middle of the cell, spindle fibers attach onto chromatids.
The key difference between prophase I and prophase II is that the prophase I is the beginning phase of meiosis I, and there is a long interphase before it while the prophase II is the first phase of meiosis II without an interphase prior to it.. Mitosis and meiosis are two important cell divisions occur in all living organisms. Among them, meiosis is a vital process for sexual reproduction.
Prophase 1 vs Prophase 2 of meiosis DURING PROPHASE I: Crossing over happens in chromosomes where genetic information is swapped from chromosome to another at a chiasma (chiasmata for multiple ...
