Presentation Transcript

  1. Meiosis • Meiosis occurs in the gonads. Its main function is to produce gametes with a haploid number of chromosomes. Meiosis differs from mitosis in three ways. Cells divide twice in meiosis, but the DNA only replicates once. Second, meiosis distributes a random mixture of maternal and paternal chromosomes. Finally, homologous chromosomes pair up side-by-side in the first meiotic division in a process called crossing-over.
