Answer:
The things that happen during meiosis I are:
- Sister chromatids are condensed.
- Homologs come together.
- Homologs separates from each other.
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.
