Detailed explanation-1: -Pairing of homologous chromosomes is called synapsis. Synapsis occurs only during meiosis.
Detailed explanation-2: -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-3: -Synapsis occurs in meiosis. During synapsis, the homologous chromosome pairs line up during prophase I. This sets the stage for crossing over, when homologous chromosomes swap pieces of genetic information. During mitosis, homologous chromosomes do not pair up, and thus synapsis does not occur.
Detailed explanation-4: -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-5: -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.
