Question

In which stage of Meiosis I does synapsis occurs?

Answer 1

In meiosis I, synapsis formation occurs in the zygotene stage of prophase-I. It is the second stage of prophase-I. During this stage, the chromosomes start pairing together and this process of association called synapsis. Such paired chromosomes are called homologous chromosomes. This synapsis is accompanied by the formation of synaptonemal complex formed by bivalent or tetrad chromosomes.
