synapsis

alignment of chromosomes along the metaphasal plate
|
Detailed explanation-1: -The events that occur in meiosis but not mitosis include homologous chromosomes pairing up, crossing over, and lining up along the metaphase plate in tetrads.
Detailed explanation-2: -During meiosis, homologous chromosomes are paired and then separated to reduce the genetic content of the resulting gamete cells. Synapsis does not occur during mitosis, because homologous chromosomes do not pair with their counterparts.
Detailed explanation-3: -Synapsis occurs only during meiosis.
Detailed explanation-4: -Synapsis is the pairing of two chromosomes that occurs during meiosis. It allows matching-up of homologous pairs prior to their segregation, and possible chromosomal crossover between them. Synapsis takes place during prophase I of meiosis.
Detailed explanation-5: -Synapsis takes place during the zygotene stage of prophase I of meiosis.
