The genes on the chromatids of homologous chromosomes are aligned with one another in synapsis. The pairs are only held together at the chiasmata at the end of prophase I; they are known as tetrads because each pair of homologous chromosomes’ four sister chromatids are now visible.
WebIn prophase I, homologous chromosomes undergo a process called synapsis, whereby they pair up to form a bivalent (or tetrad) The homologous chromosomes are held together at points called chiasmata (singular: chiasma) Crossing over of genetic material between non-sister chromatids can occur at these chiasmata Web1 jun. 2009 · Homologous chromosome is when a pair of chromosomes containing the same linear gene sequences, each derived from one parent, and a tetrad is formed …
