The key difference between bivalent and synaptonemal complex is that bivalent is an association between male and female homologous chromosomes while the synaptonemal complex is the tripartite protein structure that forms between two homologous chromosomes.

Thus, the main difference between bivalent and tetrad is that bivalent is the group of two homologous chromosomes whereas tetrad is the group of four sister chromatids inside the homologous chromosome pair.
