Light micrograph of a fetal ovary showing several oocytes (immature egg cells) undergoing meiosis (gamete formation). The oocytes are in the zygotene stage of prophase I. In this stage the homologous chromosomes begin to pair (synapsis). The paired chromosomes form dark aggregates known as a bouquet.
