Web13 feb. 2024 · Synapsis or syndesis is the lengthwise pairing of homologous chromosomes. Synapsis mainly occurs during prophase I of meiosis I. A protein complex called the synaptonemal complex connects the homologues. The chromatids intertwine, breaking apart and exchanging pieces with one other in a process called crossing-over. WebCrossover allows the chromosomes you pass to your children to have some genes from your mother and some from your father. Without crossover each chromosome you passed to your offspring would either be exactly the same as the one from your mother or exactly the same as the one from your father. 1 comment ( 13 votes) Upvote Downvote Flag more
