In which stage of Meiosis I does synapsis occurs?

Webb15 apr. 2024 · In meiosis I, specifically in Prophase 1, two homologous chromosomes(they have the same length and the same position of centromeres, but does not contain the same genetic material) partner together. This is called synapsis. Once synapsis is completed, the cross-over and subsequent genetic recombination occurs. WebbComplete answer:In meiosis I, synapsis arrangement takes place at zygotene stage of prophase-I. It is the second phase of prophase-I. During this stage, chromosomes begin to join; this is called synapsis. Does crossing over occur during synapsis? Yes, crossing over occurs during synapsis when the chromosomes are bundled in tetrads.
