Which of these things happen in "meiosis I " ? Choose all that apply.

The things that happen during meiosis I are:

Explanation:

Meiosis is a process of cell division whose objective is to obtain gametes -cells related to reproduction- that possess half of the chromosome charge (haploids). Meiosis consists of two phases, named I and II.

A summary of the events that occur during meiosis I would be

- Prophase I  

Homologous chromosomes pair up and form synapses - which can only happen in this process - forming bivalents, structures made up of two chromosomes and four chromatids.  The formation of chiasms -the synaptonemic complex- allows the crossing over or recombination between sister chromatids.

- Metaphase I  

Alignment of bivalents on the equatorial plate, with highly condensed chromosomes.

- Anaphase I  

Each chromosome, formed by two chromatids, separates and moves to each pole of the cell, a process that implies the disappearance of the chiasms.

- Telophase I  

There are two haploid daughter cells, not identical due to recombination, with chromosomes formed by two chromatids.

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
