In meiosis I, synapsis formation occurs in the zygotene stage of prophase-I. It is the second stage of prophase-I. During this stage, the chromosomes start pairing together and this process of association called synapsis. Such paired chromosomes are called hom*ologous chromosomes. This synapsis is accompanied by the formation of synaptonemal complex formed by bivalent or tetrad chromosomes.

hom*ologous chromosomes
hom*ologous chromosomes are made up of chromosome pairs of approximately the same length, centromere position, and staining pattern, for genes with the same corresponding loci. One hom*ologous chromosome is inherited from the organism's mother; the other is inherited from the organism's father.

During the zygotene stage of the prophase I (meiosis I) chromosomes starts pairing together, this process is referred as synapsis. Synapsis is followed by the development of the synaptonemal complex. The synapsed pair of hom*ologous chromosomes are known as bivalent.
Synapsis takes place during prophase I, or the first stage of meiosis. It helps to ensure that each cell created when the cell divides has a full set of chromosomes.
Synapsis is the pairing of hom*ologous chromosomes during prophase I of meiosis. The synaptonemal complex is the protein scaffolding structure present between hom*ologous chromosomes that facilitates genetic recombination.
Synapsis or Syzygy is the pairing of two chromosomes that occurs during meiosis. It allows matching-up of hom*ologous pairs prior to their segregation, and possible chromosomal crossover between them. Synapsis takes place during prophase I of meiosis.
Synapsis or syndesis is the lengthwise pairing of hom*ologous chromosomes. Synapsis mainly occurs during prophase I of meiosis I. A protein complex called the synaptonemal complex connects the hom*ologues. The chromatids intertwine, breaking apart and exchanging pieces with one other in a process called crossing-over.
In meiosis I, the hom*ologous chromosome pairs become associated with each other, are bound together with the synaptonemal complex, develop chiasmata and undergo crossover between sister chromatids, and line up along the metaphase plate in tetrads with kinetochore fibers from opposite spindle poles attached to each ...
In metaphase I, the hom*ologous pairs of chromosomes align on either side of the equatorial plate. Then, in anaphase I, the spindle fibers contract and pull the hom*ologous pairs, each with two chromatids, away from each other and toward each pole of the cell. During telophase I, the chromosomes are enclosed in nuclei.
Events that occur during prophase of mitosis also occur during prophase I of meiosis. The chromosomes coil up, the nuclear membrane begins to disintegrate, and the centrosomes begin moving apart.
Synapsis occurs in meiosis. During synapsis, the hom*ologous chromosome pairs line up during prophase I. This sets the stage for crossing over, when hom*ologous chromosomes swap pieces of genetic information. During mitosis, hom*ologous chromosomes do not pair up, and thus synapsis does not occur.
Synapsis is defined as the process of association of hom*ologous chromosomes. It occurs during the zygotene phase of prophase 1 of meiosis 1. This particular stage is not observed during the process of mitosis. Synapsis is accompanied by the formation of a complex structure called the synaptonemal complex.
