Final answer:
Homologous chromosome dyads do separate and move toward opposite poles after Metaphase I, which is true. This separation occurs during Anaphase I of meiosis, contributing to genetic diversity in gametes.
Step-by-step explanation:
The statement that homologous chromosome dyads separate and move toward opposite poles after Metaphase I is true. This process occurs during Anaphase I of meiosis, where the homologous chromosomes are separated by the spindle fibers shortening and begin to move to opposite sides of the cell. During Metaphase I, homologous chromosomes line up along the equator of the cell with their kinetochores facing opposite poles. This arrangement is vital for the genetic diversity resulting from meiosis, as it ensures that each gamete receives only one chromosome from each homologous pair, with potential variations in genetic information.
