To solve this problem, we need to analyze each statement regarding meiosis and identify the incorrect one.$\newline \bullet$Option 1:$\newline$ - Meiosis consists of two stages: Meiosis-I and Meiosis-II.$\newline$ - This statement is correct.$\newline \bullet$Option 2:$\newline$ - DNA replication occurs during the S phase of the cell cycle, which precedes Meiosis-I.$\newline$ - There is no DNA replication during Meiosis-II.$\newline$ - Therefore, this statement is incorrect.$\newline \bullet$Option 3:$\newline$ - Pairing of homologous chromosomes and recombination (crossing over) occur during Prophase-I of Meiosis-I.$\newline$ - This statement is correct.$\newline \bullet$Option 4:$\newline$ - At the end of Meiosis-II, four haploid cells are formed from the original diploid cell.$\newline$ - This statement is correct.$\newline$Based on the analysis, the incorrect statement is Option 2.
