Which stage of meiosis does notChromosomes are duplicated to produce sister chromatids during interphase. contribute to an increase in genetic diversity? Gametes that are produced during meiosis are randomly fertilized afterward. Homologous chromatids exchange sections of DNA during crossing over. Homologous chromosomes are separated independently of each other.
