Bivalent -A bivalent, sometimes referred to as a tetrad, is the association of a pair of homologous chromosomes physically held together by at least one DNA crossover. This physical attachment allows for alignment and segregation of the homologous chromosomes in the first meiotic division.
Synapse- A junction between two nerve cells, consisting of a minute gap across which a neuron is transferred.
Synaptonemal complex- A ladder like series of parallel threads visible in electron microscopy adjacent to and coaxial with pairing chromosomes in meiosis.
