Vedclass · Answer

(B) During the process of synapsis in the $Zygotene$ stage of $Prophase-I$ of $Meiosis$,homologous chromosomes pair up to form a complex known as a bivalent or tetrad.Each chromosome consists of two sister chromatids.Since a bivalent consists of two homologous chromosomes,it contains a total of $4$ chromatids ($2$ from each chromosome).Therefore,a tetrad is named so because it contains $4$ chromatids.

During synapsis,how many chromatids are present in each bivalent (tetrad)?
