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. WebHumans have 23 chromosome pairs, which results in over eight million (2 23) possible genetically-distinct gametes just from the random alignment of chromosomes at the metaphase plate. This number does not include the variability that was previously produced by crossing over between the nonsister chromatids.
