Q. During which stages (or prophase I substages) of meiosis do you expect to find the bivalents and DNA replication respectively?

Cell Cycle and Cell Division

Solution:

In bivalent formation of chromosomes during meiosis, the homologous chromosomes are arranged in pairs. The phenomenon is called synapsis and it occurs during zygotene stage. DNA replication occurs during S phase or synthetic phase which is the second phase of interphase.
