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: -Which of the following occurs during meiosis but not during mitosis? Synapsis occurs. The pairing of homologous chromosomes that only occurs during prophase I of meiosis is called synapsis.
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.
