Detailed explanation-1: -The correct option is A. Synapsis. Synapsis is the pairing of two homologous chromosomes that occur during meiosis. This takes place during the prophase stage of meiosis I.
Detailed explanation-2: -Prophase I The tight pairing of the homologous chromosomes is called synapsis. In synapsis, the genes on the chromatids of the homologous chromosomes are aligned with each other.
Detailed explanation-3: -The pairing of homologous chromosomes during Prophase I of meiosis is called synapsis. During synapsis, sister chromosomes pair closely along their entire length. A synaptonemal complex is a ribbon-like proteinaceous structure that is essential to the molecular basis of synapsis.
Detailed explanation-4: -Meiotic synapsis is the stable physical pairing of homologous chromosomes that begins in leptonema of prophase I and lasts until anaphase of prophase I. First, short segments of axial elements form along chromosomes.
