Respuesta :
The side-by-side pairing of homologous maternal and paternal chromosomes at the start of meiosis is called Synapsis.
In meiosis I, there are 4 subphases: Homologous chromosomes align themselves side by side during prophase I. They are touching each other on a physical level. Synapsis is the term for this procedure. Crossing over takes place at synapsis. Synaptonemal complex formation takes place during the meiotic prophase along with the pairing of homologous (maternal and paternal) chromosomes, physical contact, and DNA exchange through reciprocal sites of crossing over (chiasmata) between homologs.
Homologous chromosomes pair with their counterparts during meiosis and remain connected as a result of the exchange of genetic material. This process is known as synaptic plasticity. To lessen the genetic makeup of the final gamete cells, homologous chromosomes are coupled and then separated during meiosis.
