- Question 5 Review meiosis. This is a multiple answers question. Which statement is true about the meiosis? O Meiosis is preceded by the replication of chromosomes O In early prophase I, each chromosome pairs with its homolog and crossing over occurs O In anaphase I, pairs of homologous chromosomes separate O At the end of meiosis 1, the number of chromosomes is reduced by half and genetic variation is produced. O During Meiosis II, the number of chromosomes is reduced by half and genetic variation is produced.es/50898/quizzes/423789/take How to test yoursel S New Tab 13b This must be a stage of Meiosis I because O there is a spindle present.
