In prophase I of meiosis, the homologous chromosomes form the tetrads. In metaphase I, these pairs line up on the midway stage in between the two poles of the cell to type the metaphase plate.
Tetrads do not form through mitosis since homologous chromosomes will not associate for the duration of mitosis. These are fashioned in the course of meiosis that's a method of mobile division and that is applied type sperm cells and egg cells. In meiosis tetrads facilitate the Trade of genetic content amongst homologous chromosomes.
Tetrad Evaluation in genetics refers to Examination of four items shaped from meiosis. In organisms like yeast the tetrad includes 4 spores even though in the event of Neurospora the ascus during which products and solutions of meiosis are held, you will find 8 ascospores.
