How many chromosomes are in a tetrad
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. WebApr 13, 2024 · When PMCs were at the tetrad stage, two to three flower buds were randomly sampled from the control and treated groups every two days and fixed in Carnoy’s fluid. After 24 h, the fixed male buds were transferred to the 70% ethanol solution and stored in a refrigerator at 4 °C.
