The bivalent chromosomes that are generated during prophase of meiosis I comprise a pair of homologous chromosomes. Homolog pairing during prophase I must include mechanisms that avoid or eliminate entanglements between non-homologous chromosomes. In Drosophila spermatocytes. non-homologous associations are disrupted by chromosome territory formation. https://www.roneverhart.com/Lorac-Tantalizer-Toasted-Bronze-Body-Bronzing-Luminizer-5oz/
