A couple of homologous chromosomes, or homologs, are a set of one maternal and one paternal chromosome that pair up with each other inside a cell during meiosis.
In mitosis, homologous chromosomes replicate forming sister chromatids (identical copies of a replicated chromosome that are attached). Each sister chromatid is separated toward the end of mitosis by spindle fibers and divided between two daughter cells.
