Synapsis of Homologous Pairs Occurs Crossing Over May Occur
Yes crossing over occurs during synapsis when the chromosomes are bundled in tetrads. Synapsis is the pairing of two homologous chromosomes that occur during meiosis. 5 2 3 Synapsis And Crossing Over Youtube This occurs in prophase of meiosis I. . A protein complex called the synaptonemal complex connects the homologues. The main difference between synapsis and crossing over is that synapsis is the pairing of homologous chromosomes during the prophase 1 of the meiosis 1 whereas crossing over is the exchange of the genetic material during synapsis. The chromatids intertwine breaking apart and exchanging pieces with one other in a process called crossing-over. In prophase I of meiosis the replicated homologous pair of chromosomes comes together in the process called synapsis and. Independent assortment of chromosomes. It allows matching-up of homologous pairs prior to their segregation and possible chromosomal crossover betw...
