Crossing Over plays a critical role in increasing the genetic variation among offspring of sexual reproduction. → True
Crossing over is unique to meiosis. → False
Its occurrence depends on specific events early in prophase I → True
It has important consequences for the rest of meiosis and beyond. → True
Crossing over is the transfer of genetic information and materials during sexual reproduction among non-sister chromatids of two homologous chromosomes, resulting in recombinant chromosomes.
In crossing over, it is not only unique to meiosis but also occurs in body cells of diploid cells in mitosis.
In genetic recombination, the last stage is the pachytene stage of Prophase I where crossing over occurs but also extends to the other stages in meiosis and beyond.
Therefore, from the above concept, we can conclude that we've understood how crossing over plays a critical role in genetic variation.
