Which of the following statement(s) is/are not correct about meiosis?
I. Meiosis involves pairing of homologous chromosomes and recombination between them
II. Two diploid cells are formed at the end of meiosis-II
III. Meiosis involves two sequential cycles of nuclear and cell division called meiosis-I and meiosis-II, but only a single cycle of DNA replication
