Answer:

The things that happen during meiosis I are:

  1. Sister chromatids are condensed.
  2. Homologs come together.
  3. Homologs separates from each other.

Step-by-step 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.
