WebMay 30, 2024 · During prophase 1 of meiosis I, the homologous pair of chromosomes come very close together and bind tightly to each other so that they almost act as one single unit. This unit is called a bivalent or a tetrad (indicating that each chromosome consists of two sister chromatids so the sum of bivalent is four chromatids). WebDuring prophase I of meiosis, homologous chromosomes become connected in a process known as synapsis. The connected homologues are known as a bivalent (bi = two chromosomes) or a tetrad (tetra = four chromatids) The chromosomes are connected by a protein-RNA complex called the synaptonemal complex.
