WebA tetrad is an association of two identical chromosomes (4 sister chromatids), kept together by at least one DNA crossover. The two identical or homologous chromosomes link together during cell division, particularly during the zygotene stage of meiotic prophase I, to produce the bivalent or tetrad structure. great clips medford oregon online check inWebJan 4, 2016 · Tetrads are composed of two chromosomes or four chromatids.
