Weba) Interphase b) Prophase c) Metaphase d) Telophase ANSWER: B – Prophase. C. Prophase. Explanation: 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 … WebSynapsis and crossing over occur during prophase I. During metaphase I the bivalents (pairs of homologous chromosomes) are organized along the metaphase plate. During anaphase I, the homologous chromosomes (paired bivalents) separate from each other.
