WebWith n = 23 in human cells, there are over 8 million possible combinations of paternal and maternal chromosomes. Anaphase I In anaphase I, the microtubules pull the linked chromosomes apart. The sister chromatids … WebMeiosis is a process where germ cells divide to produce gametes, such as sperm and egg cells. In prophase I of meiosis, chromosomes condense and homologous recombination takes place, leading to genetic variation through chromosomal crossover. This forms a tetrad, which is made up of four chromatids (two sister chromatids per chromosome).
